i'v just bought cod4,second hand,and installed it on my pc.Problem is,though the solo campaign works with no trouble, i can't get on to the multiplayer mode.
When i try to start it a pop up comes on saying that there is a problem with the file.It then just says that windows will close it and search for a solution,but no help or advise comes up.

I know the risk buying second hand games with codes could be that the person that sold it to me has not uninstalled the game from previous pc's,but it doesnt mention,at any time,that the code is already in use..
It just won't open up!

I've tried accessing the multiplayer mode just from my desktop and also from the solo mode,but still no good.
Could anyone help me out here,please?
