Problem with Captivate 9 preview
Working on a responsive project today, I've found that there's suddenly a problem with previewing it. The normal responsive screen doesn't appear and instead I get a preloader icon that never completes.
I've tried all options - Next 5 slides, From this slide and Project - but none are working.

Does anyone know what might be causing this and how to fix it?
I've noticed two things that are different from an existing project that works fine:
1. Larger file size (50MB~)
2. The location for the preview file - the existing project preview has a link that looks like this: http://localhost:3679/HTML5Temp484021250159Pre/rindex.html As you can see from the screenshot, that's not what the current file is trying to launch.
