Ok well I did reinstall it and that made it so I could atleat get into the Tremulous menu; I can only play on select servers though, when I try and play on some servers I get the message "NET_SendPacket: WSAEADDRNOTAVAIL" I don't know how to fix this or even what I need to fix, so I need some help 
I've had that message before.
I think you need to lower your maxfps (com_maxfps).
My memory isn't great though, but still worth a try.
