Had this problem previously and thought it may have been my two week trial expiring. Opened an account last week, and tonight the problem started again.
Offline works fine, and when going online I can login and see the arenas. I can ping the individual arenas, but as soon as I attempt to enter any of them the following happens.
1) I load the textures
2) I end up in the tower with the clipboard displayed and a map
3) There are no field icons on the map, and no sound.
4) Crashes to desktop with the Windows message regarding the exe file encountering a problem and do I want to send a report.
I was online earlier tonight, and this week without any problems. Running 1024x768 with 1024 textures. Lowering the video settings yields no improvement.
