It looks like you don't have a QVM, there are many around, and easy to set up.
Download a QVM, (maybe Lakitu's with patches, look around). Put it in your server folder:
Windows XP: C:/Documents and Settings/(Your user)/Application Data/Tremulous/base/vm/game.qvm
Windows Vista: C:/Users/(Your user)/Appdata/roaming/Tremulous/base/vm/game.qvm
(Those are just my guesses at the defaults, I could be wrong)
Hope this helps! :)
Edit: I know this is a few days late, maybe you have fixed it, maybe not...
