i have reinstalled direct x and it still doesnt work, after the second or third match i play the game crashes loading the next map, ive been dealing with it for a while now any help anyone?

and second topic... GET WITH THE PROGRAM CALL OF DUTY,  YOU AINT NOTHING WITHOUT DEDICATED SERVERS!!! the only way to sufficiently keep hackers out, letting people host their own servers and have the abilities of banning and kicking and all that. plus servers are solid no crappy game play with the pitiful match finding call of duty has no offence. half the time im playing people from another continent like wtf? lol but yah im sure youd make pc players much more happy if that happened and i know it would keep more people playing and less people giving up on the series
