How many jump objects have you added to the system? There was another thread recently about that matter. Basically there is a limit to the amount of jump things you can have and Liberty is already set to the limit.
Another possible one, that can be a bugger, is the encounter list at the top. If you have an encounter in the system which dosen't have the top encounter line it'll crash. Also, if you have the encounter line, but there is no file in the encounter folder then that ones a crash too. Have you added any custom encounters?
