Excerpt: I upgraded from Stutio 11 Plus, but with 16, I couldn't get it activated. I spent 2 weeks with Corel support, all activation keys were the same and would not load, "Generated for a different Passport". Many times when trying to contact Corel, the web site would not open or if it did open it claimed my e-mail was not in their system. I gave up and ordered Adobe Premere Elements 12. I still have Studio Plus 11 on my other computer to use in a pinch.
