Help: Photoshop CS6 Mac Configuration Error 16
Help needed and appreciated.
On a Mac (10.12.1), our Photoshop CS6 workflow has ground to a halt with the [repeated] appearance of "Error:16."

Have tried following guidelines from Program Error displays while using Photoshop Program Error displays while using Photoshop but do not appear to have either an SLStore folder nor Adobe PCD folder.
Uninstalling and reinstalling Photoshop helped, but only for about a day, after which the "Error: 16" message reappeared.
During many years of using Photoshop, we've never experienced this problem.
Again, your assistance appreciated.
