Cannot import a PPT file -- no way, no how!

HI, I thought I would add to this as well. I have Office 365. Be honest, I haven't worked with Office in years, and versions with 365 thing is really confusing to me. I think the Powerpoint version is 1910 and something about the Monthy Channel: I just installed it a few weeks ago, so the versions should be up to date. 

Anyways, I can't import a PowerPoint slide into Storyline 3. I get the standard error and tried what people describe above. I also can't do anything with Presenter 13 in the Powerpoint. I can also do some things with the Articulate button in Presenter (I got the import buttons to work --- but didn't try to actually import anything)  but if I either try to Preview or Publish, there is a quick flash and then the whole presentation (as well as PowerPoint itself) freezes. I can't get out of the menu nor use any aspect of the ribbon. I can use a keyboard shortcut to create a new presentation, but other than creating a new presentation, I can't do anything. I can't even close the presentation unless I go to the dock and click there to close all presentations.
