Storyline 360 unstable

I can't say it is resolved yet as I broke up each scene into it own file for the review cycle and have not brought them together into a single file yet. BUT support did give me steps to uninstall, preform a cleanup of the registry, then reinstall. Had to do it on both my laptop and computer. I was not having issues with the other courses just this one caused issues I have never seen before and I have used ever version Articulate has released. Starting a new project and importing all scenes did not resolve it and it did not bring my master layouts when I imported - which was also odd. My final fix to this point, after you get support to help you with the uninstall, clean, reinstall...

Remove all slides except one and save as a template - only way I kept my custom layouts

Start a project using "import from story template", save the file 

Then import a single scene, delete out the one slide you had in your template, repeat for all scenes

I did have to rebuilt one scene as I could never get it to be stable

Also - I was using expanded font spacing that had to be reformatted to regular spacing, saved with a new filename, before I imported. First time I used expanded spacing so it is the ONLY thing that is different from any other course I have built.

I am not having any issues with any other course and for now, the pieces of this course are stable. I'll follow-up in this thread once I bring it into a single course, or if I bring it into a single course. 

Best of luck!
