Last night I purchased several plugins and unzipped the files and placed the folders in the Bin64/OpenPlugin folder as instructed: Only 1 out of all of them has shown up in the Plugin folder. Many are G-tools, such as RoadBuilder, Building Creator, StairBuilder, and BuildingBlocks. Out of these (and all the others) only StairBuilder actually shows up.
Nature Terrain Generator is showing in Props and Media, but there is no plugin showing to operate, manipulate, and organize its components.

Also, currently my Reallusion Hub on my desktop is not opening. I do seem to recall after my purchase I was directed to it at some point, but I apparently cannot access it at will.

I need to get to those plugins I bought. I'm a newbie to this program and already a bit discouraged.

Anyone else experienced this and found a solution?
Thank you.
