Well as I only got my Mac recently, I earlier bought Quicktime Pro for windows. I tried using the registration info on my mac, and it didn't work. Is there any way around this? Or do I need to pay for it again?
From what I've read, you buy a windows license or a Mac license so you cannot just use your old one once you changed platforms. As the other poster commented your best bet is to contact support and hopefully they don't charge you.
