Photoshop Elements 19 not running smoothly
About 3 years ago I moved Elements 11 from my old to my new iMac and it has never run smoothly. Recently I uninstalled all Adobe apps from the old computer, ran the Adobe Creative Cloud Cleaner Tool and installed the free trial version of Elements 19. It worked well with about 900 photos.
I have now uninstalled all Adobe apps, run the Adobe CC Cleaner Tool and bought and installed the regular price version of Elements 19 on the new computer. I did not want my Elements 11 catalogue to be imported into the new organiser. I wanted to start completely afresh importing photos from my Pictures folders. In “import” I chose “- - -new catalogue - - ”. My complete Elements 11 catalogue was imported (about 7000 images). The organiser is really jumpy, worse than Elements 11 was.
I do not know how this happened when I had deleted and uninstalled Elements 11 from my computer. What can I do to start with a brand new organisation using Ekements 19?
