Cannot GET /livepreview/qr.svg

I launched Captivate on my Mac and brought up a demo project.  I clicked to preview it.  It opened a tab on my computer but then said this: “Cannot GET /livepreview/qr.svg” Does anyone know a resource to help get past this or what I’m doing wrong?

Transitioning from Kajabi to Captivate

I’m currently using Kajabi to manage an online resource library.  I’m new to Captivate.  Does anyone have experience with Kajabi and what the main difference will be if I transition over to Captivate?
