I just had my first crash or freeze in about 8 hours of playing the beta. I went to the Skirmish option, it sat there saying "Waiting for NET Traversal" for a while. No games showed up. The "Create Lobby" option was greyed out. I clicked on LAN, the "Create Lobby" was still greyed out, so I hit cancel. The screen went to black, I had the control of the mouse cursor, the music was still playing, but after a few minutes it was clear that I was not getting back to the main menu. My HDD activity light was not on, so nothing was accessing the disk. Definitely frozen.
Alt-tab did not work (and I know that does normally work), so I had to Ctrl+Alt+Del. The task manager had the normal cursor, but everywhere else save the taskbar had the Dragon Commander Cursor. I had to kill it with Task Manager.
EDIT: Oh, right, because of the update, Windows wanted to get my authorization before letting it connect. That might be part of the problem, and it's certainly why it wouldn't connect.
