I can't validate my game

A friend of mine gave me the file, so I could succesfully install it. But when I tried to play it, I had to validate it, and I can’t use the ID that I got by registering on this page. Please, if someone could help me I’d be glattered, a lot of people tell me that this is a great game.

Thanks a lot.

Did you buy the game? or has someone who bought the game copied it for you? That isn’t permitted, if it’s being played by two separate people on 2 separate PCs, obviously. I may have misunderstood you though. Feel free to email me at cliff AT positech dot co dot uk
