Hi All, I retried the delete Evernote folder process. I had already done this but didn't have success. Tried again (and though I couldn't delete 2 of the files - got caught up in need permission loop) - and lo and behold it worked. I also had deleted the web version from my account (though this didn't seem to make any difference when I did a couple of days ago). So maybe doing it on a Sunday morning allowed the IT gods to smile on me a little bit and grant me a wish. Whatever... it seems to be working again.
I appreciate all the comments and contributions ... and to those others having problems - good luck.
