Looking at the Autotune logs, I do see some failures yesterday (likely due to our mistake with the voided purchase). I do see the most recent connect passed for getting Facebook App information.
If you're still having problems, let us know. The best thing at that point would probably be to Private Message us a set of super admin credentials so we can investigate on your site. You can PM me by clicking the mail icon under my picture (<----)
We'll help you get things sorted out soon.
Thanks,
Alex
