I'm running the free version of SH3D (5.2a) on my MacBook Pro (El Capitan — OS X 10.11.6) and like it so much I want to get the paid version from the Apple App Store. Do I need to be aware of anything when I install the paid version? Do I need to uninstall the free version first or can I just install right over it? I'm assuming any designs I've done will be picked up automatically.

Thanks! (btw, great program!)
