@kngstr,
Unfortunately, I was unable to open the archive you shared: error.png (11.5 KB). Please try using a file storage (Google Drive, Dropbox, etc) to share a link to the presentation file.

Sorry. I forgot to tell you.
Remove the last ‘.7z’, then decompress xxx.7z.001.
This is a file, compressed in 7z volumes
