You seem to have an active lock file which is blocking you from opening the catalog.
You need to go to the location where your catalog is stored and get rid of .lock file (do not delete any other file) and then, launch Lightroom.
Find and delete the .(DOT)Lock file in the same folder as your LR catalog file. LR most be closed when you do this.
THANKS IT WORKED
