With initially 6 players listed during the NAT traversal process for Pantheon play Demigod froze. One player dropped out. Demigod seemed locked in the NAT sequence, with nothing further happening (the progress animation was playing, but nothing further occurred). I finally CTRL-ALT-DEL`d and saw a FATAL ERROR window in the taskbar next to the normal Demigod window. All it said was "FATAL ERROR Demigod" followed by the version number of Demigod.
This has actually occurred previously a few times. If I click on the ERROR window my machine hangs at a grey screen, fullscreen. Nothing further happens.
If it helps, I can`t recall ever playing a Pantheon game with more than a single human besides myself.
My 'On-Access Scan' was disabled.
Newest Demigod code (as of today March 19th 2009) run.
