when i start visual studio 2010 c# .. and open my application i got this. it stopped responding and gives me that message in the picture once my application is opened but other application works fine.

then i debug visual studio 2010 .. and i got the exception
Unhandled exception at 0x76a0b9bc in devenv.exe: 0xE0434352: 0xe0434352.

EDIT: i tried to open the .exe file in project folder in debug folder and i got this.

how to fix that ? what should i do ?
thanks in advance.
i’ve figured out what happened .. my form got 3 usercontrol that i made before.. one of those usercontrol has a customized progressBar which is a library .. for some reason that library stopped working .. so i removed it .. then added again from that usercontrol .. then the application worked.
