I have been able to download transactions from my Citibank account to my Bank account in QuickBooks Desktop for 2 years, but now suddenly it does not recognize my Bank account in QuickBooks.  The account has online access activated.  It has not had an issue up until this week.  How do I resolve this?  I do not want to lose the past 2 years of data, so I do not want to create a new account.  Please advise.
