I bought a new notebook with Windows 7 (x64) installed on it.
I downloaded and installed WL Essentials,with only Messenger selected to be downloaded.After the installation process was done,Messenger came up and I filled out the spaces for e-mail account and password and I have select "Sign in".The blue and green icon started to rotate,so I thought it's OK.After about thirty seconds nothing has happened.I waited for a while and the some errors came up.I've checked every error on this forum and other forums,but nothing was the solution.
Later,I installed Pidgin(http://en.wikipedia.org/wiki/Pidgin_%28software%29),I've sign in and it was OK,so I noticed that the defect is not on the account.While Pidgin was still running I tried one more time to sign into my WL Messenger,and again it was the same problem,but Pidgin has disconnected from my account,and Pidgin "told me" that I sign in form a different location,and that means WL Messenger has signed in on my account but the program is still on the "signing in" screen.And one more thing,while trying to sign in,when I receive a e-mail ,the notification shows up.
That all is on the v14 versions of WLM,but on the v15 and the today released WL Essentials 2011 after the installation process is done,and the Messenger shows up,an 80004002 error comes up.And after every start of Messenger the error comes up without me pressing the "sign in" button.

So,where is the problem,I sign in but the WL Messenger "stucks" on the sign in screen.

PS.Sorry for my bad English.And if you have any additional questions,feel free to ask.
btw.I've tested one more thing,I entered some random letters in the password field,and after a few seconds,there was a message that the password is incorrect.So it signs in,but I can't see it.
