Alright. I have been trying to figure out the problem but can't seem to get around it. Every time I try to play one player, it asks for my CD key. The weird thing is I put it in and Battlefront shuts down. (Before anyone asks I have actually bought the game)

The only problem with this is that I can not install Custom Maps in the add on folder. I can still play online with standards.

Any ideas? I am kind of desperate to play again.
