已去除混淆代码，用reflector 已找到关键代码，但不知道怎么修改，还请高手帮忙

软件有试用限制，每次15分钟，只能发10个帖子。程序用de4dot去除了混淆代码。用reflector,找字符串：

private void MAIN_Shown(object sender, EventArgs e)
{
try
{
      try
      {
         if (!Functions.piv)
         {
            int num = this.method_3();
            if (Functions._Getstamp(DateTime.Now) > num)
            {
                  base.Invoke(new MessageHelper.de_showInfo(null, (IntPtr) MessageHelper.showWarn), new object[] { this, string.Format("试用时间已满，请联系QQ{0}购买Vip权限。", Class34.string_4) });
                  base.Invoke(new Class33.Delegate22(Class33.smethod_0), new object[] { 1, this });
            }
            DateTime time = DateTime.Parse(Encryp.TripleDESCryptoDe(Class26.smethod_0("MyGod")));
            if (Functions._Getstamp(DateTime.Now) > Functions._Getstamp(time.AddDays(4.0)))
            {
                  base.Invoke(new MessageHelper.de_showInfo(null, (IntPtr) MessageHelper.showWarn), new object[] { this, string.Format("试用时间已满，请联系QQ{0}购买Vip权限。", Class34.string_4) });
                  base.Invoke(new Class33.Delegate22(Class33.smethod_0), new object[] { 1, this });

这里是试用时间限制，每次15分钟，请高手指点，这里怎么改。

private void method_7()
{
if (base.InvokeRequired)
{
      base.BeginInvoke(new MessageHelper.de_showWarn(null, (IntPtr) MessageHelper.showWarn), new object[] { this, string.Format("非V*i*p用*户限*制每*个论*坛顶*贴数为{0}。\r\n需*要购*买V*i*p联*系Q*Q：3*17*5*850*7*1", Class30.serverCfgWS_0.get_LimitReplyMaxPerFm()).Replace("*", ""), "权限不足" });
}
else
{
      MessageHelper.showWarn(this, string.Format("非V*i*p用*户限*制每*个论*坛顶*贴数为{0}。\r\n需*要购*买V*i*p联*系Q*Q：3*17*5*850*7*1", Class30.serverCfgWS_0.get_LimitReplyMaxPerFm()).Replace("*", ""), "权限不足");
}
}

  private void method_7()
{

      base.BeginInvoke(new MessageHelper.de_showWarn(null, (IntPtr) MessageHelper.showWarn), new object[] { this, string.Format("非V*i*p用*户限*制每*个论*坛顶*贴数为{0}。\r\n需*要购*买V*i*p联*系Q*Q：3*17*5*850*7*1", Class30.serverCfgWS_0.get_LimitReplyMaxPerFm()).Replace("*", ""), "权限不足" });

看着好乱，下载一个看看吧

if (Functions._Getstamp(DateTime.Now) > num)
            {
                  base.Invoke(new MessageHelper.de_showInfo(null, (IntPtr) MessageHelper.showWarn), new object[] { this, string.Format("试用时间已满，请联系QQ{0}购买Vip权限。", Class34.string_4) });
                  base.Invoke(new Class33.Delegate22(Class33.smethod_0), new object[] { 1, this });
            }
            DateTime time = DateTime.Parse(Encryp.TripleDESCryptoDe(Class26.smethod_0("MyGod")));
            if (Functions._Getstamp(DateTime.Now) > Functions._Getstamp(time.AddDays(4.0)))
            {
                  base.Invoke(new MessageHelper.de_showInfo(null, (IntPtr) MessageHelper.showWarn), new object[] { this, string.Format("试用时间已满，请联系QQ{0}购买Vip权限。", Class34.string_4) });
                  base.Invoke(new Class33.Delegate22(Class33.smethod_0), new object[] { 1, this });
            }

这个方法整个删除试试，如果报错的话

把这个重新赋值一个最大时间值试试 DateTime time = DateTime.Parse(Encryp.TripleDESCryptoDe(Class26.smethod_0("MyGod")));

软件测试起来不方便啊。。。。。要不多改几次试试就应该行了

删除代码后，虽然程序不会出错，但仍然不能运行，没有反应。
DateTime time 又如何修改呢？

发现两个函数都会出错：
method_13,method_7
在reflector里，怎么查看是哪里调用了这两个函数？
method_13代码如下：
private void method_13()
{
if (base.InvokeRequired)
{
      base.BeginInvoke(new MessageHelper.de_showWarn(null, (IntPtr) MessageHelper.showWarn), new object[] { this, string.Format("非V*i*p用*户限*制每*个论*坛顶*贴数为{0}。\r\n需*要购*买V*i*p联*系Q*Q：3*17*5*850*7*1", Class30.serverCfgWS_0.get_LimitReplyMaxPerFm()).Replace("*", ""), "权限不足" });
}
else
{
      MessageHelper.showWarn(this, string.Format("非V*i*p用*户限*制每*个论*坛顶*贴数为{0}。\r\n需*要购*买V*i*p联*系Q*Q：3*17*5*850*7*1", Class30.serverCfgWS_0.get_LimitReplyMaxPerFm()).Replace("*", ""), "权限不足");
}
}

  private void method_13()
{
if (base.InvokeRequired)
{
      base.BeginInvoke(new MessageHelper.de_showWarn(null, (IntPtr) MessageHelper.showWarn), new object[] { this, string.Format("非V*i*p用*户限*制每*个论*坛顶*贴数为{0}。\r\n需*要购*买V*i*p联*系Q*Q：3*17*5*850*7*1", Class30.serverCfgWS_0.get_LimitReplyMaxPerFm()).Replace("*", ""), "权限不足" });
}
else
{
      MessageHelper.showWarn(this, string.Format("非V*i*p用*户限*制每*个论*坛顶*贴数为{0}。\r\n需*要购*买V*i*p联*系Q*Q：3*17*5*850*7*1", Class30.serverCfgWS_0.get_LimitReplyMaxPerFm()).Replace("*", ""), "权限不足");
}
}

method_7代码如下：
private void method_7()
{
if (base.InvokeRequired)
{
      base.BeginInvoke(new MessageHelper.de_showWarn(null, (IntPtr) MessageHelper.showWarn), new object[] { this, string.Format("非V*i*p用*户限*制每*个论*坛顶*贴数为{0}。\r\n需*要购*买V*i*p联*系Q*Q：3*17*5*850*7*1", Class30.serverCfgWS_0.get_LimitReplyMaxPerFm()).Replace("*", ""), "权限不足" });
}
else
{
      MessageHelper.showWarn(this, string.Format("非V*i*p用*户限*制每*个论*坛顶*贴数为{0}。\r\n需*要购*买V*i*p联*系Q*Q：3*17*5*850*7*1", Class30.serverCfgWS_0.get_LimitReplyMaxPerFm()).Replace("*", ""), "权限不足");
}
}

  private void method_7()
{
if (base.InvokeRequired)
{
      base.BeginInvoke(new MessageHelper.de_showWarn(null, (IntPtr) MessageHelper.showWarn), new object[] { this, string.Format("非V*i*p用*户限*制每*个论*坛顶*贴数为{0}。\r\n需*要购*买V*i*p联*系Q*Q：3*17*5*850*7*1", Class30.serverCfgWS_0.get_LimitReplyMaxPerFm()).Replace("*", ""), "权限不足" });
}
else
{
      MessageHelper.showWarn(this, string.Format("非V*i*p用*户限*制每*个论*坛顶*贴数为{0}。\r\n需*要购*买V*i*p联*系Q*Q：3*17*5*850*7*1", Class30.serverCfgWS_0.get_LimitReplyMaxPerFm()).Replace("*", ""), "权限不足");
}
}
