Since I couldn't find any documentation of a new Evernote install downloading NOTHING (documentation was all about update syncing problems), and I had just downloaded Evernote and nothing had happened on it, this is not what I would expect would fix the problem, but it turned out to be what did the trick. I moved the Evernote app and the Evernote folder in Library->Application Support to the trash, restarted my computer, downloaded Evernote again, and as soon as I logged in the Evernote app, all my notes downloaded. Weird. But thanks for answering my post.
