I downloaded the free trial a few days ago and after a few hours decided to upgrade to the full package. However does the trial version then automatically upgrade to give me the full access or do I have to uninstall the trial and then reinstall the new one?
Also I tried to save a short video I made, but it went all the way down to just a few seconds remaining then froze there, is there something I am missing?
It's the same software, - it's the licence that changes, and enables more access.
