Elements 2018: Catalog could not be opened due to an internal programming error
I have recently upgraded Photoshop Elements from 2011 to 2018 on my Mac. All worked fine, I had successfully converted the catalog from my previous version. Meanwhile I added a few hundred additional photos, tagged them, created new tags and so on.
Now on starting the program I get the message "Catalog could not be opened due to an internal programming error".
I had no shutdown of my Mac in between the time that the program still worked. iTunes etc. are not activated.
Does anybody have an idea, what to do? I need access to my >50,000 tagged photos.
