I have been getting a CC-503 error for months (more than 6) on my accounts. I have followed other threads discussing this where Quicken states they are aware of the error but nothing has been done to fix this. It's very frustrating when you call both the banks and C/S for Quicken and do not get any answers for a service I have been using since early 2004. My banks have NOT changed and they see no error from their side. Help???
