I have had COD2 on my laptop (XP) since it came out in 2005 and have had no issues with it either single or multiplayer modes.
All of a sudden it starts locking up on my son in single player mode. He would start the game and it would fail within the firt minute. I only play online, so never notcied any issues right off. Then all of a sudden the Punkbuster selection was OFF and when I selected it to ON, it totally threw me out of the system.
After a while we decided to uninstall/reinstall everything.
That seemed to take care of it for a couple days, but now this morning it's doing them same thing. I try to play online, was denied entrance into a game for not having Punkbuster selected, went back to select PB and it boots me.
I searched all over and could not find anything that discribed this problem on any of the COD2 site.
Hope someone can help.
