Restart your computer. Some program might be using that file you're trying to edit. (pwn.exe might be )

[rappy93]

Rename the pwn file you're editing.

No, but tnx , i fix with someone in general file..

It's mostly because of an internal compiler error which resulted in an abrupt end to the compilation process, and because of that the pawncc process(the .dll pawno uses for compiling the .pwn into a usable .amx file) is already in use because it never ended.

Changing the file name will work however restarting your PC or manually ending the process should work.
