Are you trying to run it under 64bit linux?
When I tried to play, I got lots of errors like these:
Error: file ui/ingame.menu, line 1: file ui/menddef.h not found
Error: file ui/ingame_options.menu, line 1: file ui/menddef.h not found
Error: file ui/ingame_system.menu, line 1: file ui/menddef.h not found
Error: file ui/ingame_player.menu, line 1: file ui/menddef.h not found
...
Grab a newer verion of the ioq3 binary from here: Www0.org
Then overwrite "~/desura/common/iourbanterror/ioUrbanTerror.x86_64" with "ioq3-urt" (you'll need to rename it).
Who do we talk to, to get this fixed within the system?
