how to find serial number for Logic pro 8
My Macbook just had its logic board replaced. I'm attempting to use Logic Pro 8. First thing, it asks for my serial number. I've tried entering numbers found on various parts of the packaging; none are valid. Can someone tell me where to find the proper serial number? If there are mutiple numbers in that location, how do I recognize which one is the serial number?
Thanks!
