Not trying to be a jerk here, but just to ask an obvious question...Did you uninstall the game before installing the gold edition?
I mean...did you have GC:II Dreadlords, the full game, before purchasing gold edition?
If anything, uninstall all versions of the game. Reinstall only the gold edition, as it is Dreadlords AND Dark Avatar.
I installed the game on both of my computers, now the desk-top had no problems with the Dread Lords, but when I installed the gold edition, the game started freezing at random. So I thought it might be my machine, then I installed the game on to my laptop and I got the same results
Because you stated that the game was on two of your machines, and it's not working on either, I have to wonder if its
not your system or hardware...
Please answer, I'm going to bed soon. Will check back tommorrow if anything. But give this a shot, okay?
IF you have downloaded any mods, save your mods folder, but don't replace

until you have tried to start up the game.
