Steinberg support team sent me another link to download the full version Padshop/Padshop pro from their download updates page. But still they didn’t sent me License key and told it will run in pro mode for 30 days.
When I run the installer, and select 64bit, it simply shows if I want to uninstall / Reinstall or no change the Padshop. Still I tried to load Cubase and its opening on Padshop not the pro version.
