The Union Platform (tm)

Hello.

I wanted to try to compile the chat application but I could not do this(.
If you could give me advice how to compile it please I would be very grateful.

I downloaded and installed Adobe Flex Builder 3 and Adobe Flash CS4 Professional and I downloaded ReactorGUI_1.0.0.179_Alpha6 and other downloadable packages from the site (union,UnionAdmin_1.0.0.84_Alpha6,Reactor_1.0.0.652_Alpha6).

I unzipped it into a folder on D: and started a new action script project UnionChat in AdobeFlexBuilder 3.
I copy-pasted a code of the chat from the page http://www.unionplatform.com/?page_id=44&page=7
and tried to compile with CTRL-F11,but I received two errrors:

==========================================================================================
1046: Type was not found or was not a compile-time constant: IClient. UnionChat/src UnionChat.as line 65 1267465850812 1
1046: Type was not found or was not a compile-time constant: ReactorEvent. UnionChat/src UnionChat.as line 26 1267465850812 0 ==========================================================================================

Help would be very much appreciated.
Valentin.
