Just did the update on a freshly installed Toast T Pro 14.
The updated Toast crashed upon launching several times.
Removed the prefs from the Library folder, just in case. No change. Still crashes.
Deleted the Toast folder from Applications.
Reinstalled the un-updated Toast Pro, which now works — as well as it originally did.
At least I can use it for Blu Ray data backup while Roxio works the bugs out of this not-ready-for-primetime update.
