If the problem is that on-line downloads aren't working, you might want 
to try breaking the connection between the on-line portion of the 
program and the internal accounts, then re-establishing it with the new 
account number. You should be able to this through Tools> Online Banking 
Setup... and using the Accounts tab once the AQBanking Configuration 
screen comes up.
