Is anyone's MSN f'd up too? Cause I can't message anyone right now.. and I have a project DUE... TOMORROW!!!
If it wont work re-install it. It takes 2 seconds so that's not much. It never happens to me but some advice here.
Have you even tried exiting then relaunching the program? Because that's what I always do and it works. Stay signed out for a few minutes too.
