I made a backup of MW2 on my computer, took the backup files to my 2nd PC and installed.
Now i get "common_mp.ff missing" when i start Multiplayer, but SP works perfectly.


Can i get the file from anywhere without having to download 11gig ?


Edit:
The other question is... why dont i have any stars in Special Ops on the 2nd pc?
I am using my own steam account.
