[RESOLVED] App suddenly changes size (0xc000007B)

[Imperoto]

So, I made an app on visual basic 2008, all cool and stuff, but now I'm experiencing a major problem. When I run my program it just works fine, but after some time (when I don't use the app) it suddenly changes from 42,5 KB to around 100 - 130 KB, and when I try to run it I get this error;

The application failed to initialize properly 0xc000007B
Click on ok to terminate the application.

So if I extract it again (zipped it), it works again and after some time I get the error again, so the file in the ''zip'' doesn't change.

I can ensure I got no virus whatsoever on my computer, nor in my application.
I just reinstalled my pc to see if it fixed the problem, it didn't

(Windows XP Home Premium)

I attached the source code ;-).

Thanks in advance,
Jordy.
