Hello @Dave Mayer
Could you try this for me and see what it does. Can you go across the top to tools -> online center. Hold CTRL + Shift on your keyboard and in the top left of the popup box click on contact info. In the account you should be able to select quicken bill pay. Once here click on the 4 boxes that have online in the box. Once you have the 4 selected click refresh.
Once this is done try seeing if you're still getting the 318-A error. Please let us know how it goes!
