I have been having the same issue.  I spoke with support and they said their engineers were working on it.  It worked for about a week and now it has been 15 days and it has not worked.  I have two accounts at the same bank and one feeds perfectly and the other does not.  I don't see that this is a bank issue, it is a Quickbooks issue.  We pay way too much for this product for the continued problems it causes.
