Installing

I am trying to install this on my new laptop.But poxy Steam says that the CD key is already in use.Is there any way or a mod to circumvent having to have bloody Steam?Or am i stuck with it?BYW this is a pukka version of the game that i bought brand new.

Steam is the only route.

Contact Steam support and Sega support with all the purchase info requesting a new one.

Bugger,sod it then.Cant be bothered.
