Maybe Toribash is broken its just a guess.
I had the same problem some time ago (Toribash crashed after a minute), I reinstalled toribash and everything was fine.
One time Toribash even crashed 1 second after it was started because the name of a replay was to long.
(Just put your old Replay-files in the new Toribash folder, then should toribash work and you still have all your replays!)
