Please give us the following basic information:

 I have forec quit

That could/would have resulted  in LrC not cLosing properly, resulting in the lock file not being removed. The lick file is created when you open a catalog, it is deleted when you close LrC. Purpose is to prevent multiple instances of LrC running using the same catalog.

Bigger question is why were you forced to force quit.
