Hi! I'm having a little problem and needed some advice. I have Final Cut Pro 4 and have installed it on both my iMac and my brothers imac just fine (both of which run jaguar). Recently, I just got a brand new ibook G4 and tried to install it on there. The problem is, when it asks for my first serial number it goes through just fine. But when I type in the "Previous Serial" text box the little "OK" button doesn't light up, not allowing me to continue on with the installation. I'm not exactly sure what the problem is but it's really frustrating me and I was wondering if anybody had any ideas. I was wondering if maybe its because my new ibook runs panther, but i'm not sure if that would have anything to do with the previous serial number.
