I was making a Processing sketch using OpenGL. Up until now, I was able to export the sketch as an application and everything would work fine. But now, when I open the .exe application, it just gives me a grey screen and nothing happens. The code is fine because it works when I run it in Processing. 

I get loads of "could not delete" and "could not copy source code" errors. Why did it work before and how can I fix this error?

I would appreciate any help :)

Muhasaresa :D
