Hi. Ive used TV for years (free home use) but just today upgraded to Premium. I received my invoice, followed the email instructions to activate TV on my devices, but it indicates its still the "free" version on all but one of my devices, and the other says its the 7 day trial version. So, I tried entering the license key included with the invoice, but it says its not valid! Not sure what to make of this and I need to be able to activate all my workstations. Any help would be greatly appreciated.
