I just ran into this and did not keep a complete set of steps, so I strongly suggest you contact support.

Rather than delete everything (many items in OptionYY you will realy want to keep), it involves renaming several to file to  fileOLD. I was very fortunate to get an exceptionally good systems person on my first call and we resolved the issue and I retained all except a few 2019 organizer settings that I had done over the weekend.
