Tip: MSN Messenger Live Error 800706be

Recently my MSN Messenger suddenly stopped working, no matter how many times i tried to login, it still failed. Eventually I came across this web site http://windowslivehelp..com/solution.aspx?solutionid=48cb38e4-dffa-4250-8671-8b44fe19383b which solved my problem. The problem was actually related to corrupted contact data in my local computer.
