After updating PS to 21.2.0, I was so unhappy with the CR plugin (12.3) that I contacted Tech Support and they gave me a link to revert back to previous plugin. That has screwed EVERYTHING up. Now, any RAW / DNG file brings up a strange CR screen with all of the controls missing and it's now obviously all corrupted. I've tried uninstalling and re-installing PS from CC site and it is still screwed up. Tech keeps giving me links that are supposed to overwrite the old plugin but I can't get any detailed help.
