Hi Howard. I looked through some of your recent contributions. Most of your profiles are either unlisted or private, and I don't see anything in the contribution log that provides any hints about lost data. So without being able to see much there, and not knowing what the lost data looks like, I'm drawing a blank. I can only suggest that you try contacting one of the mentors and share some additional detail with them about what data isn't being accepted or what requirements you haven't accepted. Perhaps they can help. Sorry.
