I purchased this midweek, and like another reviewer, my redemption code was invalid, and failed in any attempt to contact Air. I am therefore in limbo - not sure where my money has gone, or my software! I am concerned that this is a scam. I would advise everyone to avoid buying anything from Air for now (maybe not KVR, but I doubt I'd get any help from them as this is the Marketplace).
Hopefully things will change and Air will get back to me.
