I recently borrowed a library book but was unable to finish reading before it expired. So, I put my name in the waiting list and am now ready to read it again. However, ADE gives me a "Document license expired" error. Does this mean I can't borrow the same book twice?
Note that I've deleted all he books from my library, so there should be no record of the previous borrowing.
Overdrive (the back end provider for most libraries) is aware of the problem and we are working on it.
What Jim Lester is saying is that there's a problem with other software that
is causing this error, and Adobe and that software manufacturer are 'working
on it'. While that doesn't really answer your question, at least you know
it's not your fault.
I'd contact your library and tell them the problem you have. Maybe they've
worked out a solution that bypasses the software 'bug'.
