I think we have got to the bottom of the cd-key not being recognised issue. The problem occurs when you trying to run the game with an account that does not have full access permissions to the registry. This is normally when running from a non-Administrator account.
If you believe that you have logged on with an administrative account, try logging on using an alternative Administrator account (or create a new Admin account) and then enter the cd-key using that account.
If you are still unable to enter the cd-key, Windows XP users should check their registry permissions as follows:
a) Click Start > Run, in the open box type REGEDIT
b) Go to HKEY_LOCAL_MACHINE > SOFTWARE > Codemasters
c) Right click on the Codemasters entry and select 'Permissions'
d) Ensure that the user account (that you are trying to run the game on) has "full control" allowed
