    Lightroom 5 will not start but shows as running in task manager?



      I'm using Lightroom 5.7 (64 bit) on a Win7 machine and it was working perfectly until a few days ago. Now for reasons unknown to me, it will now not start correctly. According to Task Manager it is running but nothing appears on screen. It shows as a running process using about 15,020k. If I try and end the process it will not stop until I have tried 4 or 5 times.

      I have tried renaming the preview file to force it to build a new file, and optimizing the data base and it ran once, said it was checking the catalog, and then reverted to the same behaviour.

      If I can get it started I can revert to a backup database.

      Help appreciated.
