Yes, that was really annoying. The problem didn't came from the game but from the anti-copy protection on the DVD-Rom. The retailler politics of no refund was a bad new and at the time, the local costumer support phone number was not active. As I bought it for 5€ instead of 40€ on sales, I binned it and forgot about it. It was a Steam offer that made me buy it again, knowing that if it didn't work, I could get a refund easilly from them. I did not regret my purchase.
