I just reinstalled windows vista, And mw2 and installed aIW on it. But when i start it up it says iw4mp.exe stopt working. I found more ppl having this problem and having it fixed with downloaden .NET Framework 4 and Microsoft Visual C++ 2008 Redistributable. But i got those 2 installed and it's still not working for me.
And btw why is my old post deleted since it has nothing to do with aIW being down. Because i have still the same problem right now.
