I own a copy of Logic Pro Studio on CD and have done since... 2010? Just having done a fresh install of Mac, I copied everything back onto my HardDrive, but I can no long open Mainstage? It crashes everytime I try to open it, I'm running 2.0.1 And I can't update on the App Store because I don't really want to buy a programme I've already bought? Any tips would be great. Thanks everyone!
