Yes - please contact us support (at sign) exportmybooks.zendesk.com. We'll check on the file and see if we can open it. If we can't we'll fix the issue. It may be necessary to resubmit your file - we only retain them for 30 days and then they are automatically deleted. I know someone recently had an issue with the password on the .qbb file.  The password worked for us but not for them - I think they were trying to log in as Admin and that's not what we intend so there was some confusion. We've updated the videos and documentation to address that.
