Capturespace "presentation is invalid" when browsing for presentation to upload

I am trying to use Capturespace under the “Add New” > “Capturespace Recording” > “Presentation On” > “Browse”. When I tehn select the .pptx file to upload, i get the following error:
“The selected presentation is invalid. Invalid presentation will not be recorded” What does this mean, and what is causing it. I uninstalled and re-installed. Tried several different .pptx and .ppt files. Same issue.
