I've been using Windows Live Beta for couple of weeks now...
Not much time later,update showed up.
Downloaded,couldn't install,all errors.I said,that's ok,this one is fine to me.
(had windows onecare scanner if anyone is interested)
Weeks later,couldn't sign in to my main e-mail,but could to another one.
Ok,i signed in to another one,and started to add friends and things...
I started to search and things,but some sites weren't loading,when i would click on download @ http://download.live.com/ , an error would came.
So it would for all g.live.com sites.
Week later,i couldn't log on without an update,tried to download the update,there came the errors from the last try of the update.
So i've deleted all windows live beta programs to try install and download again.
Deinstalled,but couldn't download @http://download.live.com/ cause the download wouldn't load.
Asked my friend,to send me installation file,worked for him,but..
This what shows to me after starting of the installation file.


Anyone,help please...
And the same thing shutted down my updates..

I'm running Windows Vista Ultimate.
