New windows live messenger?

So, this morning (Korea time), I come to work, plug in my computer, sign into Windows Live Messenger, and get a notification window advising me to upgrade. I said to myself, “Why not? It’s free.” So, I installed the upgrade and now I can’t even get the silly program to launch. What am I doing wrong here? All I want to do is log into my Windows Live Messenger program and chat with my friends online!

do you have admin rights at work? Sometimes you think you might be installing it but really arent. In the meantime google meebo and use that
