Okay, sure, I'll help you.
First off, before we do anything, do you have the tremded.exe in your Tremulous folder? It should be in:
C:\Program Files\Tremulous
or
(Bla bla bla, wherever the hell your folder is)\Tremulous
If its not there, it should be in your Tremulous folder, not the /base folder, not anywhere else. It should be in the folder where tremulous.exe is.
Next, check where your Qvm is. It should be in the /vm folder:
C:\Documents and Settings\<Your PC's name here, its usually Administrator or the name your computer shows at the top of the window when you hit "Start">\Local Settings\Application Data\Tremulous\base\vm
Now, start up your server again. If the same result happens, use a different Qvm (Like the p-g-qvm, google the latest version 1.6.5). If you want, I can set up a guide with pictures for you. Cheers.
