i have just got a new mac and have tried to load guitar pro5 on the new machine, it has loaded but when i try and open it, it just quits. when i reloaded it it did not ask me for the licence number or anything, and i think this may be the problem, but i have no idea how to enter this in. i have tried to log onto guitar pro web site as i did register the software but i cannot find any help area, can anyone help me?
