I had to elevate the issue to Quicken Support.
Issue resolved. I contacted NYCB via secure message and inquired about the CC-508 issue. My inquiry was provided to the NYCB IT department who removed a "pop-up" from my account profile even though I was not receiving any pop-ups when I logged in to their website. Now I am able to download transactions again.
