investment transactions now jumbled, account passwords missing

es114 Member ✭✭
I update weekly. This AM I updated to 39.23. Getting unidentified transactions from 3 months ago in various investment accounts with multiple transaction mismatches. One step update also indicates 4 accounts without password and restricts me from adding current existing passwords. Have tried using previous backups but same problems occur.
Have been using Quicken for over 20 years and never seen it this bad. Please help.
