I've been on XBL for a week now, and I went to try to play some NBA2K3 tonight and I couldn't sign in. I launched the network troubleshooter and it said I was in fact connected. This happened in NBA2K3, NFL2K3, and MotoGP. Each time I went to the troubleshooter and it said I was connected. Has this happened to anyone else? I'll be checking out the XBOX Live Beta page soon, just curious.
