stuck on temporaryRepairedCatalogue.lrcat-journal

I was trying to repair a corrupted .lrcat file, but as soon as the dialogue appeared that it was being repairing it suddenly disappeared.  Rather than allowing it to finish I foolishly tried to do the same action again.  Then I couldn't open LRC at all so I uninstalled and reinstalled it.  However, now I don't even have a lrcat file at all.  Instead all I have is a file named temporaryRepairedCatalogue.lrcat-journal.  Since I am rather new to this couild someone explain to me how I can resolve this issue and get LRC working again?
