BT is a whole nuther kettle of fish , you need to either use gameType="Botpack.CTFGame" or GameType="Bunnytrack.Bunntrack" the second one works with maps of Prefix 'CTF-BT-' the first with 'BT-"
if you are using the CTFGame (Gametype) then rename the Map from 'CTF-BT' to 'BT' or .. search for the already renamed version through google.
I gave up on BT , because I had problems getting the latest version to work properly fullstop.
post back the MapVoteLA 'Customgame[x]=' settings and I'll see if I can help you
