Problem with Sibelius on Crossover

[brian9271]

I have one problem when trying to open Sibelius on Crossover, it says I already have it installed and that my 15 day trial has passed already and that I haven't registered it, but I already registered, before when I installed it I typed in everything, it won't open now, I managed to do it on my Vista, but what is wrong with it on Crossover, I managed to get to creating a new sheet, but then I don't know why. Any help would be great thanks.
