File locked for editing by unknown user

I utilized Open Office Documents to create a text document. When I saved it, I saved it as a .doc
When I tried to open it to continue with my writing, it opened with all of the text as pound signs ( # ). I found the locked temp file and deleted it as I saw in a posting on this site. It still did not open. I tried converting it into another file. Nothing has worked so far. Does anyone know how I can retrieve this file somehow?
