My problem : yesterday i launch the game and it show me the COD mw 2 picture here no problem but after i had a black window in all my screen and after a little black window in the middle of my screen. can you help me plz

reinstall mw2, thats 100% no ban, if u are banned u can show @ steam > settings, above ur accname

Maybe install a new driver, and reinstall Divx. or delete all the mapps in steam (not steammaps) and let steam update.
