I've been dealing with this upgrade issue for years. A few months back, an Adobe "rep[" tried to place the blame on the user. Told me the disc-based version was removed because we (you and me) were pirating Adobe Premiere. Yup, our fault. All I have learned is, if you create anything, keep that version of Adobe CC. When Adobe updates, in order to line their pockets and keep you buying new versions, they eventually eliminate the older versions. I had a sic of Adobe c6s, but then they blocked people from even using the discs they PAID FOR! Oh well, no new project going now, so it will be a while before I am once again dealing with crashes, workarounds, and fixes! Isn't it glorious having to work harder, pay more, and enjoy less????
