But seriously...
a: Caps off... we can hear you
b: Wrong forum. There's a Support/Bugs section. This is "General Discussion" = Offtopic
c: Title: Nexuiz. What on earth were you think it reveals athing about your true problem?
d: Way to report problems effectively: write a brief report about the error: how and what happens, online/offline, in case online which server et. Operating system? Windows? Xp? Vista? Other version? Linux - what distribution? Mac? What version?
System specs (Especially video card)? Do you have the latest drivers installed for it?
These are the things we need in the first place to be able to help you.
