Hi, this problem is driving me crazy. I paid for a the latest version of Toast Titanium 11 Pro for my Early 2008 Mac Pro 8 core with OS X 10.8.2. The download went smoothly, as did the install. But when I go to run it, I get the lovely spinning wheel, and must Force Quit the app (shows as Not Responding).
The Corel support pages were of no help. I have wasted many hours trying to re-install it and also to install updates.
I ran an earlier version of Toast on a Mac Mini and it was awesome. This is very frustrating!
