Interactive presentation

I have an interactive presentation that seems to be corrupt. I can access all of my other files just fine but I really need to access this one. It took a good 20 hours to create. I don't have h5p installed in my server.

Any suggestions? Is there any way for users to get access to a previous version of a file?

Hello

Is it possible to import multiple slides into the interactive presentation?, am converting ppt into jpg then would like to import or upload all jpgs into an interactive presentation.

Thanks

interactive presentation 

authoring on H5P website as moodle does not have this option for our school as we are waitng to upgrade to 3.##

when text highlighted, trying to select paragraph style or text size or any pull down menu, the options do not display, but flash breifly only.

tried in chrome and MS Edge.

 Maybe significant that my desktop updated MS files over the weekend, but my laptop hs ot, and it works fine for that device??
