Thank you! After running "Tool Hub," with no errors found, I searched around and found: File/Utilities/Verify Data....which found errors and did rebuild my data. I hate doing this because I had a problem after rebuild with one client. It did work this time, however.
Very frustrating that they don't put all troubleshooting under "Help." Its like looking for the needle in a haystack sometimes!
Oh well! It's fixed and I can move on.
Thanks so much for your help!!!!
