LibreOffice 4.2 hangs on File Recovery

Tried to open a LibreOffice file, but instead a LibreOffice Recovery window came up. It said that I could click a button to recover a specific file. (That file did not crash, but I did just do a curve fit…) The window just hangs. I can’t take any actions other than to minimize it.

Tried deleting all LibreOffice files, but anytime I launch any LibreOffice 4.2 app, this Window shows up referring to the same (now deleted) file). (Aside, I copied the files to a stick and opened them in Excel, then saved them in .ods format…loosing the curve fit, but keeping the data.)

How do I get this working again? Is there some file in some directory somewhere? Thanks in advance.
