Why are my asset downloads getting stuck?
Do your asset downloads start, then stop? Does the resume button begin the download again, but then get "stuck" in this cycle?
This is usually caused by the location of the Greyscalegorilla Asset folder that you've defined. It needs to be a location that C4D has write access to. We normally suggest somewhere in the User folder, like in "<username>/Documents/gsg_assets/". You'll need to create the folder yourself and here is a video which explains the process in greater detail.
