Gotcha. Yeah, I see one there. Big green button with a down arrow saying "GET IT NOW" lots of whitespace below and then a smallish rewaterpressure logo. Because of the whitespace, the button very much looked associated with the paint.net download text above, not with the rewaterpressure logo below.
I also received the less bad (but still bad) text-based "start download now" one the same page. You convinced me. Editing my parent post above.
EDIT: for those curious, here's what the page looked like on the page load mentioned above: http://imgur.com/SisOXNT
