Having Conversion Issue from epub to PDF/DOCX

[readingis]

I am having some issues with conversion with a book, hasn't happened in a while. all my plugins are current.

I am not sure if it's DRM issue; previous DRM books Calibre able to remove.

I am getting follow error message, again not sure why this is suddenly happening.

Also, another question, on some conversion in the past, after the book was converted, everything was off in the book. Is there reason for that?

thanks
Jeff

According to that you are converting a PDF file not an EPUB file and the PDf file is password protected.

oh thanks, so I guess there's no way to remove the password protect? Isn't that what DRM is (sorry if that's a dumb question) thank for replying

calibre does not contain any DRM removal code. You can use a third party plugin for it, or remove the DRM before importing the file into calibre.
