Error Importing (checked the archives already)

My issue is similar to this one from the archives (that topic is closed).

The answer was that perhaps there was an issue with the file and to try converting it to PDF. That helped the original poster. I am using Adobe, just like the original poster…so I thought that would help me to. It didn’t.

When I tried to convert my file from EPUB to PDF, I got another error saying it is a protected file and can’t be converted. Is there anything that can be done? If not, how do I know for future purchases which files I will be able to import to LINGQ? Thanks.

You need to remove the DRM using Epubor Ultimate or Calibre. Adobe Digital Editions just allows you to open the file.


Oh, I see. Thanks so much for you help.
