boneboys 7988 Posted January 1, 2013 I am led to believe that there is a key-changer tool provided by GOG.You will have to use it to validate your game (run as admin).Might help, might not. Share this post Link to post Share on other sites
hawk777th 0 Posted January 1, 2013 (edited) I replaced the Serial key when the game first launched with the one GOG provided.Just keep getting bad version when trying to join servers. Edited January 1, 2013 by Hawkd Share this post Link to post Share on other sites
