Don't know if it's too late now, but get your money back and buy another pair from a more durable brand such as Burton or Union.
Personally, I would not use binding that have airbags for baseplate dampeners in the first place, because airbages usually "bust out" and if they don't, they're still likely to do so. I know that's not your problem, but I'm just saying that it's more potential for breakage if you do get another pair of Raiden bindings.
(I quoted "bust out" because Raiden actually stated, in a Transworld Gear Guide I think, that the more common EVA padding busts out and air bags don't do that. Seriously? How stupid do they think we are?)
