Same here, I just got 14 MBs of errors.html and nothing else.

Tried running it twice, all I get are emails informing me they can't do it ( http://i.imgur.com/zlFgQX4.png ).

This error might have come up because you have an open Gmail client session running (or another Google service), or simply that the new service is completely overloaded right now.

Same here. I got a 64MB errors.html file. No actual data.

Hopefully some human is checking the logs and will be fixing this.

I checked this with a new/small account and it gave me the mails al right.

+1 same issue.

I have 10.6GB of email. Wonder if that might have something to do with it.
