If I start my app on reboot, MyApp crashes after few seconds

Question

I'm running on Windows 7 and I've a problem with my app at boot. Within my app I use some threads and external dll (sqlite3.dll, etc...). I've included these lines at first of my start.exe file:

RegistryKey rkApp = Registry.CurrentUser.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", true);
String p = System.Environment.CommandLine.Replace("vshost.","");
String pp = p.Remove(p.Length-1);
rkApp.SetValue("MyAPP", pp);

If I start my app manually from exe file (or with VisualStudio) works correctly. If I start my app on reboot, MyApp crashes after few seconds.

Why I've this problem?

EDIT: I've attached crash log:

We have solved my issue. FYI: If you use Directory.GetCurrentDirectory() on application that should be start on boot, we have to verify correct path (actually is windows/system).

Thanks for your help! With Dynamic debug all works correctly!
