[Help needed] Compiling/Debug(F5)..

[HackProvider]

I made some changes in the newestcoserver.proj, everything was oke, but after 2/3 hours. I started to change some more things and suddenly i couldn't Compile(f5) anymore, when i press f6 it says everything went oke and that they putted it in the output folder, but when I press F5 I get no errors, but in the output it gives an error,, nothing is wrong with the coding.. its just weird..

please look at it ><
