I installed " Chaos Theory" and inputed the CD key as requested, but each time I do, I get an error message. NOTE: I am copying the CD key characters from the game book owners manual. Please help. Thanks

I have the same problem.

I loaded SCCT on my system (Windows Vista), and it wouldn't load properly (driver error). After upgrading with Patch 1.05 and installing the proper drivers, it appeared to load, but now it isn't accepting my CD Key. Anyone else run across this issue, and if so, how was it resolved?

There's the key you want if you are in the US.

The key on the booklet is the Spy v. Merc key.
