Flash CS5 + Adobe AIR2 class error

Question

As you all know, Flash CS5 is now released. It is confusing me as AIR2.0 is still in beta. so is the air2 in flash cs5 stable or not?
I tried to use DatagramSocket class in Flsh CS5 but failed
import flash.net.DatagramSocket
Up to this point, everythings ok
var ds:DatagramSocket = new Datagramsocket()    
FAILED.VerifyError: Error #1014: Class flash.net::DatagramSocket could not be found.
    at runtime::ContentPlayer/loadInitialContent()
    at runtime::ContentPlayer/playRawContent()
    at runtime::ContentPlayer/playContent()
    at runtime::AppRunner/run()
    at global/runtime::ADLEntry()
I tried replacing the air2 beta 1,air2 beta 2 as stated in the release note but it still fialed..
Any idea anyone?

Hey mate you're not alone - I bought Flash CS5 and having been using it for a couple of days now, When I made a new AIR app, I can't install it because it says (in the installer window):
"This application requires an update to Adobe AIR that is not available for your system.
Please view the system requirements for Adobe AIR and update your system accordingly."
Yet when I click on the system requirements link it would appear my PC has everything needed to install the app. I have since updated AIR to AIR2 beta 2. No change.
Pardon the french but what the hell? Flash CS5 only creates AIR2 apps, no option for AIR1 exports, and AIR2 isn't even properly released yet... ADOBE FAIL!!!
