Okay, so i have recently download mono to open an .exe file on my mac. I have a Mac OS X Version 10.7.5. I can locate the file but it when I exucute the file it says "Cannot open assembly 'G.R.O.exe': File does not contain a valid CIL image." The .exe is G.R.O.exe. Please help i am rather newbish at these things so please put everything in stupid terms... or at least teach me a bit.
