Trouble opening Lightroom 4.3

Feb 2, 2013 11:43 AM

Hi,

 

my computer crashed last night while I was using Lightroom.  Since then I cannot re-open the program to resume work.  I keep getting the following message: "The Lightroom catalog names "Lightroom 4 Catalog" cannot be opened because another application already has it opened."  Can some one please help me to resolve this issue?

    Navigate to where your Lightroom catalog is. If there is a .lock file there, delete it.

    Normally the lock and journal files are deleted on exit. The lock file is there to prevent several instances of Lr opening at the same time.

     

    With Lightroom closed, it should look like this, .lrcat and .lrdata only:
