CD key not recognized

After I updated my client to the latest version, the client keeps telling me my cdkey is not valid. I have re-entered it several times. Game verifies it is legit. I have checked the cdkey in my registry and it is correct as well. I bought and have used this key for over a decade now. My key is real, it is legal but the latest CoD4X keeps rejecting it. Can you look into this?

Cod4x has nothing with that. I have original cod4 from steam and cd keys working well. Can you try run your iw3mp.exe as Administrator, then rewrite cd key again and join an server.

Oddly enough, that worked! Thank you.
