I have Quickbooks Pro 2016 - I can not upload bank statements - It says that the bank account that I am trying to download to does not exist.  It does exist and it is listed in the chart of accounts.  I can not edit it because it has transactions attached.  I can't download manually because of the same issue.  I have all updates installed - one of which is supposed to be for this problem.
How am I supposed to get my statements downloaded to be up to date and reconcile my accounts?
