I'm the same way, it hadn't synced for 2 months - pw was bad, I could just cancel & it would let me in & was storing locally. Yesterday the upgrade installed & rebooted, would not let me in w/o resetting pw, and now opening web client & all my recent work is GONE.
Can someone please tell me if there's a way I can recover all these? How could an update just blow away local data that wasn't synced??
