    Improper shut down of computer - now won't run lightroom error "This is already running in another catalog - close that application first."

      I'm using Windows 10.  I was opening lightroom when my computer ran out of battery and shut down. Since then I can't open Lightroom(4).  Instead I get a message that says in effect "this is already running in another catalog - close that application first."  But it's not running.  I have "uninstalled" the program and then reinstalled it.  I still get this message. Help help help.
