I havent played galactive civ 2 for a while and in the meantime Ive competely upgraded my computer due to a motherboard failure (so new processor, mem, gfx and reinstalled windows). After installing gal civ 2 again over the top of my old installation (I kept my data partition) it wont let me run the game, and comes up with the error "Game appears to be validated but the serial number or machine SID do not match".

Does it tie in your serial number to your machine set up? if so, how can I go about getting the game running again (with all the updates)?
