Have you too learned to expect the "Unexpected Response Format" on your .Mac account?

I know that Apple is powering up to convert .Mac service to the Mobile Me thing, but I've been getting this error screen constantly for a couple weeks now. Happens when I open emails, when I send emails, when I try to delete emails... I have also frequently been advised that the system is not capable of deleting messages at all. I'm trying to be patient in anticipation of the switch, but wondering now if my experience is common. (and it's not like this is a FREE service)
