NFS HS2 No CD patch

[grist]

Hey,

I have 2 computers in a LAN. I've purchased one copy of the game and have installed it on both machines. I've applied the NO-CD patch and it works great on both. Now here's the problem: If me and a buddy try to connect to the same server online I'm able to get in fine and he get's an "Invalid CD Key" error message. Is there anyway to bypass this so we can race on the same server?

Thanks!!!
