How did you update?
To what version?
What is the Help/Info showing in the current version when there are no photos?
Is the library showing anything at all?
thanks for your time. sorry for not including the info. updated when i checked for updates. the up date is to version 5.7.1. The library looks as if im starting from scratch. Am I going to have to reload my cat?
If you have updated from 5.x to latest 5.7.1, then usually there is nothing else to do.
Depending on the preferences you have set it opens with the most recent catalog or the catalog selection window. https://helpx.adobe.com/lightroom/kb/catalog-faq-lightroom.html
Try this: Choose File > Open Catalog, navigate to the location of the catalog you want to open, and click Open.
If you are not sure where the catalog is located, search you disk for *.lrcat
Default location is here:
Windows: C:\Users\[user name]\Pictures\Lightroom\Lightroom 5 Catalog.lrcat
Mac: /Users/[user name]/Pictures/Lightroom/Lightroom 5 Catalog.lrcat
Sounds like the update to 5.7.1 create a new empty catalog and set it as your default catalog.
In the menu /File/open-recent/ see if your previous catalog is listed there.
i tried what you said and nothing opened up.
