Credit card online banking setup stopped working

[Chris Szilagyi]

Hello:

Recently our Discover credit card online banking stopped working. It 
seems to be caused by our credit card number being changed, I think, as 
the time it stopped was around the time they changed it. Originally I 
went in to the AQBanking setup and just changed the account # there, and 
tried to download transactions and get the "no transactions for the 
selected time period" message.  I then tried deleting the online account 
in the AQBanking setup, and re-created it, but still get the same 
error.  I did notice that at the end of the AQBanking setup wizard where 
you select the associated GNUCash account, the GNUCash account has the 
old credit card # on it under the Account ID column, but I am not sure 
if that really matters, I haven't been able to find any way to change 
the Account ID.  If it doesn't matter anyway, then I'm not concerned 
with it as long as it works.

Am I doing this correctly and does anybody have any ideas of something 
else I can try?  I appreciate the help.  Thank you.
