I bought the downloadable version of the game, so I won't get a disc or manual :/Same problem here. I had an update for steam. Then I put the FM disc in and pressed play and it still says BETA in the bottom corner :/
EDIT: I also purchased FM 14 from Game
EDIT 2: I think I have figured out how to do it. Click on where it says "add a game" on the steam library and type in the code that is on the back of your game manual and it should work!
