Whats wrong with my Windows Live Messenger?

It normally would sign me in automatically, but now the small icon on the bottom of the screen has a cross on it.

Then the trouble shoot comes up, and I pressed the repair, and all the suggested problems get ticked off, therefore it should start up...but it doesnt, it has the trouble shoot come up again!

I tried installing windows live again, to see if it gets fixed, but the problem has gone??

Whats wrong with it? What should I do??

Thanks
