In the beginning a lot of those that bought the game (disk) from Gogamer had the same problem.
I do not know how it was resolved since Gogamer went offline about that time.I think they still have an Ebay store.

If you got it via a d/l then talk to the site where you got it.If it is a disk do as Dano suggested and call your retailer.
