Can't import PowerPoint slides into Storyline 360.

Hi,

I just installed the free trial of Storyline on to my computer and can't get any PowerPoint files to import.

I followed the link to see the reasons why it might happen and can't figure out what's wrong. Similar to Julian, I have the following:

Password protection - not the case

Unsupported version of ppt - I have PowerPoint 2016, although it says version 2006 (don't know what that means)

Not having latest service pack - updated

Security settings - this is my own PC so I'm an administrator. Are there any particular settings I need to check/uncheck?

Presentation doesn't start with slide 1 - presentation does start with slide 1.

The Microsoft Office that I have is a subscription product from my workplace...could that be the issue?

UPDATE: Thank you Misun!  I had the same problem and now it works!  It wasn't a new laptop but it looks my office subscription was using the web based version...even though it looked exactly like the local one.  Thanks again!
