I asked on IRC, and was told to post about it here.

 

Basically, I start iw4m.exe, login and shortly after I see the menu the game crashes. Also, I cannot see the error that it gives me with the alt-tab method so I don't know if I can give coded details.

 

But if anyone has an idea on how to fix this, I'd appreciate it.

I had the same problem,turns out it is 'Couldn't load image 'preview mp_compact' error (I mentioned it in my topic)

You neet to dowload the DLC from torrent and extract it into folder of MW2.That should fix it

Its a bug i think. NTA is fixing it now I THINK.

NP crashed, NTA is fixing a second bug in NP now.
