Here is the problem. Every other account on my Windows Live Messenger work fine, but when I use my account, i get an error that says "Your contact list is not available right now, please try again later." But my account works on any other computer. How can I fis this?

Thanks!

I've occasionally had that when I've not realised I'm already logged in on the same computer....are you sure that Messenger isn't already running with that same account logged in?

If not then just wait a while, it's possible that they're doing work on one of the servers ahead of the forthcoming new release of Messenger.  Try it again in a few hours and see what happens
