I've really done it now! Can't log in.

After verifying that the My SQL version was the latest (following the steps on this thread: http://wordpress.org/support/topic/cannot-update-to-32-on-media-temple?replies=40) despite the auto-updater saying it wasn’t, I went ahead and manually updated my WP version following the steps outlined here: http://codex.wordpress.org/Updating_WordPress
My site seems to be functioning normally but when I attempt an admin login to my site now, I get a fullscreen message saying “You cannot update because WordPress 3.3.2 requires MYSQL version 5.0 or higher. You are running version 4.1.11.” NO I’M NOT!!
The WP manual update steps say “If you see a “failed update” nag message, delete the file .maintenance from your WordPress directory using FTP. This will remove the “failed update” nag message.”
I checked my files via the FTP site and couldn’t find any .maintenance file.
I’m at a loss here. Any advice on where to go from here? Thanks!
