JamJar, Flex 2 - A Little Worried

So Flash Player 9 and Flex 2 are both available now, and I finally have the chance to show off what they can do. I've been bragging up Flex 2 to all of my colleagues, many of whom simply don't get the Flash Platform at all. I'm hearing great things about the JamJar demo, and it sound like a perfect app to show off the power of Flex. Except that when I run it, I get this:

ReferenceError: Error #1069: Property hasDefinition not found on
flash.system.ApplicationDomain and there is no default value. at
mx.managers::SystemManager/getDefinitionByName() at
mx.managers::SystemManager/http://www.adobe.com/2006/flex/mx/internal::addingChild() at
mx.managers::SystemManager/http://www.adobe.com/2006/flex/mx/internal::rawChildren_addChildAt() at
mx.managers::SystemChildrenList/addChild() at
mx.managers::SystemManager/http://www.adobe.com/2006/flex/mx/internal::initialize() at
mx.managers::SystemManager/::initHandler()

I have a "Dismiss All" button and a "Continue" button, both of which yield the same result: a lovely blue-green screen with a nice gradient (you know, the standard Flex background). That's it.

I updated my Flash Player, but that's all I can think of to do... I've been a Flash developer for years, and I am at a total loss. Imagine when the average user comes up against one of these error boxes!

I knew AS3 would not fail silently, and I've always had a feeling that was a bad idea. But, I guess I just figured I'd get my code 100% right. But if the Flex team can't get it right, what chance do I have?

I've got a feeling there's more going on than buggy code. Maybe my Flash player didn't update itself correctly - that would be a bad thing too. I really want the Flex platform to succeed (I want to make a living at it!), but if this kind of user experience becomes common, it will only give ammunition to the anti-Flash crowd and make it a tougher sell.
