I would like to try your suggestion, but after rebooting my computer (since Premiere would no longer load), I now get a message that my subscription has expired even though I had a staff members uninstall the subscription version earlier today and spend a lot of time getting our licensed CS6 version installed.
I really do appreciate your input and we had been wondering if this was either a caching or drive association issue, since it all started with the connection of multiple external drives. But I no longer have time to remove and reinstall all of our software. Again.
This is a nightmare, I paid for a full version of CS6 and our business is now immobilized because Adobe showed no record of our paid upgrade, so when I went to download the software we had paid for I used the only option shown, which was the CC option. I already wasted 30 minutes of my time on a tech support call just to figure out where I am supposed to get my software. Now it looks like I'm going to have to waste a lot more time on yet another tech support call just to get the software that we paid for to work.
Adobe showed no record of our paid upgrade
I'd start by solving that. Until that shows up, you won't be installing CS6 with a perpetual license.
