Hey, I tried to play multiplayer today and it gives the 'ol ban. "Your CD code is not authorized to play this game"
Are the servers shutting down? I haven't done anything deserving a ban especially on every single server..
My friends use my dvd-rom code but they never play online.
What's up?

I can join SWGO Hero Assault just fine. (Haven't tried others.) You're not supposed to give away your CD key under any circumstances other than when you sell your game. Your issue is most likely with the fact that your friends are using your key as well.

That means that you are banned from the server.
