I have an epub that I copied to my Kobo using Calibre. At one point I was able to read it, but now when I try to go back and read it again (to access the notes I took while reading it), I get an error message indicating it's encrypted with Adobe Digital Editions DRM when that is most definitely not the case. (It's an epub created from a Google doc). There's no apostrophe in the title so I don't think the problem mentioned on the wiki is the issue here:

Is there any hope for fixing this problem short of deleting the book and copying it over again? I'm really hoping the notes I took aren't gone forever.
