I reinstalled both gtkradiant and Tremulous (making sure to clean up all settings files before reinstalling) and then followed this guide
http://tremmapping.pbwiki.com/GtkRadiant1_5-Win32 still no textures come up (when I press 't' a window comes up that is empty both 'Show All' under 'Veiw' and 'Flush & Reload Shaders' under 'Tools' do absolutely nothing). Is there something else you have to do before textures come up?
BTW gtkradiant is C:\Program Files\GtkRadiant 1.5.0 and tremulous is C:\Program Files\Tremulous
[EDIT]
I figured out the problem, the engine was set to c:Program Files\... instead of c:\Program Files\...; I really hate window's directory scheme, but I can't get X working properly in freebsd right now

Thanks all who helped me.
