Actually, the beta version of Windows Live Messenger is out 7 months, not 2 years.
Nevermind that Beta thing, I've had problems with it when I first got it (4 months ago ) but ever since, not even a problem.
Besides, if you go to the download location where you got this one ( 9.0 Beta ) you'll see that it's the same program, but Beta no longer stays with Windows Live Messenger 9.0
