Re-install question

I have Premier Elements 2019.  There were some directories still in the Program Files (x86) directory that were labelled Photoshop Elements 13.  I moved these out of the Program Files (x86) thinking they were no longer needed.  Now, Elements 2019 cannot ever load its workspace and spends a lot of time looking for its plugins.  I can eventually get it going by going back to the .exe file and starting it there but the opening "splash page" or the Desktop icon are no longer opening the progream.  I moved the Photoahop Elements 13 files back into the Program Files Directory to no avail.

I still have the orignnal downloaded install file.  I presume that I need to uninstall the Premier Elements 2019 program and reinstall it.  I presume that  my photo file with the tags, albums, etc. will still be available unharmed.  Is this correct?  Any other suggestions?  Thanks
