Did you get the screen where it asks for your serial number, like if you were installing a program from disk? I've somehow missed the "authorization" on mine a few times, and get the same thing after the Uboat missions add-on download I got for my v1.whatever disk. I also have a Gold Edition disk, and I've got the one version set-up on one computer, the other on another, and me and my boys sometimes have "elimination tournaments"...
