Call of Juarez - possible idiot alert

[Schnippzle]

Right,
Got Call of Juarez free with my Sapphire card however the key provided on the back of the paper cd case doesnt work with the Starforce protection client. It keeps saying that the key provided is wrong but I really cant find any other key to use. Furthermore, when I put the key in and it tells me its wrong, the Starforce client changes the key when I go back to put it in again. Not only does it change the actual letters of the key I provided but it also changes the format of the key. Any help would be much appreciated but I feel a really obvious answer coming along.

Not sure but if its a O then it might be a 0 or if its a W it might be 2 V's also I's are sometimes 1's

Tried the 0 or O variations and I dont think there are any W's in the code. Will have another look when I get home tonight.

E.D.I.T.: The game installed fine with the cd key provided but its just the Starforce protection client that launches as I try to launch the actual game that doesnt like the provided cd key.
