I have the same issue as KarlaD back on April 15th. I have an online connection that doesn't work. I can't deactivate it or reset it because it claims I have downloaded transactions that haven't been accepted. I don't see any downloaded transactions. I followed all the steps and got the same results as KarlaD. She copied each transaction to a new account and deleted the old account. I have 7692 transactions, so that isn't an option for me.
I need a solution that doesn't involved recreating this account by hand.
I am using Classis Windows Subscription version of Quicken.
