I've been playing the demo for a couple of days and bought the download today

I had no problem joining or hosting in the demo version (once I got the port-forwarding sorted out....great tutorial at www.portforwarding.com). But now find that I can only host races.
Each time I try to join a race I get the "Could not contact server" msg. Any ideas would be appreciated.
Thanks
