Can't open Lulu files
I've always been able to open my files on Lulu (using epub.) I need to open to check on them after uploading to lulu. But suddenly I can't open my files anymore. I get a message stating that "The office xml filecannot be opened because there are problems with the content."
This applies to every file that I have on Lulu. All of the same files that I have stored in documents open with no trouble. Has anyone else run into this kind of problem, or know how to fix it?
