inspeak communicator windows vista beta 2 build 5384

Hello Reader, my installation of Windows Vista was successful and most chat programs installed with out any problems eg. Yahoo Messenger, MSN Messenger, Paltalk.
But InSpeak Communicator will not run !
If any one has been successfull please let me know how you got InSpeak Communicator to work Please.
After I installed and I run InSpeak Nothing happens, I goto Task Manager and see that InSpeak is using 100% CPU usage, I have to end task on this application, I tried many times redownloading plus installing, I even ran the Installation file in compatiblity mode all OS's and tried running InSpeak in compatibilty mode all OS's after install, but InSpeak still will NOT open up, any suggestions (solutions) will be greatly appreciated.
I have installed Java and Macromedia flash player.
Cheers MagicBytes :)
PS. Really love the new Windows Vista, keep up the good work Microsoft, looking good !
