mw2 lib not working anymore.

[Some1weird]

Title.

Was gonna host something fun for me and my friends to play on but..

Game crashes after i press load game

So i tried running as admin(tho i have uac off), both steam and lib
disabled avast, and windows firewall
used the cleanup .bat thingie
tried redownloading, diffrent version.
Triple checking i dont have more then 1 version open
Tried messing around with mw2's setting, and setting it to safe mode.

The game works just fine on my other acc, without lib ofc.

1.06 gives me .net framework error on start, but i can just hit continue on it while 1.00 for example doesn't give it. all version crash.

Strange thing is this used to work for me earlier, but now it wont do anything.. :S

All help appriciated.

Messy text i guess, but im in a hurry.. sorry about this D:

Try reinstalling .NET Framework Download Details Microsoft .NET Framework 4 (webinstallatieprogramma)

I also have this a lot, usually goes away when i restart my computer. You could try reinstalling Liberation 1.6
