I had the same problem, Blackburn knows about the defect. All you have to do is call their 800 number and if everything goes as it did for me, just tell them your name/address and they say they'll send a replacement head. We'll see if it gets here in the next 7-12 business days.
btw, the new replacement head isn't the same dual one that you and I have, it is a new one with only one insert that can apparently fit both dunlop (car tire) and presta (skinny bike tire).

There's one on eBay right now.
