Load Button Is Not Available In Add-On Panel

Hi @mWitt26 , thanks for reaching out. It looks like this may be a problem with the Integration tools, but it is hard to know for sure without having more details of the error. Did you download both the add-on zip and the integration tools zip for Blender? If when you load the integration tools, do any errors appear on the system console?

To open the system consle on Window/Linux, in Blender navigate to Window > Show console log. On Mac you'll have to open Blender via Terminal app. When the terminal is open, use the following command to open Blender:
/Applications/Blender[YOUR_VERSION].app/Contents/MacOS/blender.

Best,
Aldo
