I just bought a new computer. Installed my NR2003 and can't get online. Tells me my cd key in already in use. I can still sign on with my old computer no problem. What can I do to fix this problem on my new computer? Any Ideas?

Have you tried it again yet, on your new computer? Your CD key can be locked for a couple of minutes after logging on and off Sierra with your other PC, mine was even locked for 2 hours after I was discoed from a server, I couldn't get back on Sierra until that race was over.

If it still doesn't work, try to reinstall the game, maybe you entered a wrong key...
