Can someone decode this XARA error message?

[craftech]

Got this today when I opened my regular Xara project that I work on.

"Problems have been found with some data. The data includes mismatching liveshares. The problems have been fixed with default values."
The signup page for MailChimp mailing list (external) is gone and the generic page is back. One other page is missing now that was internal. Is there an archive of all of this buried somewhere within Xara 12?

Thanks,

John

Not sure what happened. Found a backup and loaded it. Still pages missing even from old backup????
