Can't upgrade catalog 14.5.1 => 15.0/15.0.1
I tried optimizing and checking for integrity serveral times. I can't get my catalog to upgrade. There's only this message:
Lightroom encountered problems when trying to update the format of the catalog fileand cannot use this catalog in this version of Lightroom.
It sends me to a tech note that has nothing to do with my problem as far as I can tell. My OSX is up to date an on v26
