BB Torch :: IMAP Suddenly Not Recognized?

I've had my BB Torch for about a year and it's worked fine with my email.Yesterday out of the blue it stopped receiving my gmail messages (my other email is working fine). But I did get a message "from" Blackberry saying "Action required, update settings for ****@gmail.com to TURN ON THE IMAP SETTING FOR ALL MAIL IN YOUR GMAIL ACCOUNT"My IMAP IS enabled. I tried disabling it, then re-enabling; I've tried removing my gmail account from my BB and recreating it; I've repeatedly "activated" my gmail account on my BB (each time I DO get a confirmation that my account has been activated), I've tried "wiping" my BB and starting over; I've "re-registered" the device on the network, I've deleted my email accounts in BB, removed the battery, reentered and "revalidated" my accounts. Nothing seems to workEach time I go back into "settings", my gmail shows as "invalid account. Please Validate"...I re-renter my passcode, get the acknowledgment that "your password has been successfully validated", immediately followed, again, by the "Action required" message from blackberry. I have repeated the process of setting up my gmail in my BB about 15 times...each time getting the validation confirmation, sometimes getting a message telling me that my account is set up correctly and that I should begin receiving email in about 20 minutes.
