Did you ungraded your elements catalog from a older version.
Which version of Lightroom are you using?
Yes, I upgraded from elements 7(?) when I bought 11.
Using latest version of Lightroom CC (latest one that is possible to install) as I'm trying to try it out.
Yes, I've listed the stuff I've tried from that page in my initial post.
I had checked that page prior, so all the point refer to stuff there :-(
But thanks for the pointer to the page.
(Although the page is somewhat out-dated as the path to the .plist-files have changed.)
