This first happened a few weeks ago; everything had been fine, but then I did a one-step update, and nearly all my accounts (from at least 7 financial institutions: Citi, Chase, BofA, Fidelity, Capital One, Amex) have a CC-800 error. I read how to fix the error, and the fix worked - but it took about 2 hours to deactivate and reauthorize all my accounts.
Today it has happened again - nearly all my accounts returned a CC-800 error. Very frustrating.
No, I have not done a file restore, and I use Quicken only on one computer.
