Lightroom 5.3 encountered an error when reading from its preview cache and needs to quit
Re: Problem with Lightroom startup

My guess is that the preview cache somehow got corrupted. To fix it I would navigate to the folder where your catalog is stored, and move the Lightroom 5 Catalog Previews.lrdta folder to a location outside the installation path like your Desktop.
By default the Previews folder is located at \Users\[user name]\Pictures\Lightroom on a Windows computer, and /Users/[user name]/Pictures/Lightroom on a Mac.
Now start Lightroom, go to the Library Module and select "All Photographs" in the Catalog panel, then click on Library > Previews, and choose the previews option you prefer. This will rebuild the entire preview cache so depending on the number of photos you have it could take a while. Once completed, close Lightroom and restart and you should be fine.
Once you're up and running again you can delete the Previews.lrdta folder you moved to the Desktop.

Hi Betsy, welcome to the forum!
Don't panic, it's just the preview cache. Find your catalog on the hard drive - usually in the Pictures folder called Lightroom 4 Catalog.lrcat by default. You'll see a *Previews.lrdata folder there. Rename it and restart LR.
LR will have to rebuild previews, but then everything should be ok. You can let LR rebuild the previews as you need them, or you can select them in Grid view and go to Library menu > Previews > Render Standard Sized previews.
Once you're happy that everything's rebuilt, you can delete ...
