Have you tried, first of all, setting your security to default, & adding the sites you are trying to purchase to your trusted sites list?
I'd also advocate ensuring explorer is running with the most recent updates. There may be some more sinister reason for http secure not binding, & in that instance I'd personally be happier knowing the browser won't let me (or my wife!) do anything. If you want more specific assistance fixing explorer, PM me & I'll run through it with you. You may have gathered from the dutch oven thread I've had a lot of experience helping people get onto our own site!
