OK,
I have no problem with launching the game up to a point. After I have launched, played for a while and jumped out a few times the game refuses to launch. It just flashes up to a black screen then dumps back into windows. No events are written to the application log. If I log out or reboot I can resume the same process. The game will launch fine a few times then crash out everytime after until I relog or reboot. It looks like its leaving something running in the background without showing on the Task Manager but I might be wrong. Either way, the program isn't exiting nicely.
