Hi there, @AnotherFrustratedCustomer.
The error OL304 occurs when the online service you're using and your Financial Institution is unable to recognize the account or it's no longer active. To help you get sorted out, I suggest contacting your bank to further assist you with the error you encounter on your end.
Then, to answer your second concern, let's run the Verify Rebuild Utility Tool. This way, we can fix the minor data issue in your company file. I'm here to guide you how.
