Ok heres the low-down, I installed the same copy of my Retail UT2004 on 2 pc's using the same serial since I only have 1 copy. I can't play online on the 2nd PC because the serial is already in use, is there a way to sort this prob out ? And incase your wondering I phoned up Atari and they say they can't do anything and to go out and buy another copy ! Stingy Fockers. Somebody please help, thanx.
