You helped me find the cure!

SOLUTION FOUND:

I began to download bank transactions on week at a time. The very first week would not work and gave the OL-222 error. I noted the dates and then downloaded another week of transactions that started at the end of the first week of transactions that I had downloaded. This time the file opened and the transactions imported without issue. I then attempted to download the remaining transactions that started immediately after the successfully downloaded 2nd week of transactions, a balance of about 7 weeks of transactions. They downloaded and imported without issue into QuickBooks. This indicated that the 1st week of transactions that would not open is where the issue would be located. Next, I will download the 1st week that would not open or import, one day at a time, When I pin down which day is the problem day, I will open that day with Windows 10 Notepad and locate the error, then edit the error and resave as a .qbo file. Then I will import the edited file into QuickBooks. Fortunately for me, I have a lot of experience with computer issues and having to do repairs. I feel sorry for the average person that has to try and figure out a solution.
