I'm using ADE with a Mac and have successfully downloaded library books for a few years; suddenly today the books are downloading to the Finder but do not show up in ADE so that they can be put on my Nook.

Is anyone suddenly having trouble using Adobe Digital Editions on a Mac to download library books?  I have been using this to load books on to my Nook and suddenly, out of nowhere, everything is downloading to the Finder app.  ADE pops up like it always has when I download from the library website, but the book does not show up there.

Has something changed?
