I'm desperate... I had Quicktime Pro v6. I guess during an automatic update, I upgraged to Quicktime v7, and it's no longer Pro. I tried to get Pro using my software key but that didn't work. So my question is: how can I go back to Quicktime v6? Do I have to trash Quicktime v7 and redownload v6, and if so, where do I find v6? Okay, so then, Mac Mail erases any of my emails after four or five days. I haven't been able to find anyway to stop this in Preferences. Does anyone know what I can do to keep all my emails until I delete them? Thankx for any help!
