When uploading my GEDCOM file I had 20 pages of surnames added to my profile. I didn't want all of those. Now I'm deleting them, and every now and then I get the following error:

URL /genealogy.aspx
Username 331817
Error Cannot insert the value NULL into column 'UserNo', table 'FTDNA.dbo.ResultSummary'; column does not allow nulls. INSERT fails.
