Shoutbox

i can log on to msn fine...and everythings lurvely until i try and open a conversation window with someone or they try and talk to me.  i get a msn messenger box thingy with a red circle with a white cross in it that says

"We were unable to start a conversation with <contact>.  You may want to try again"

its really weird...and on other xp user accounts, msn is fine...i dont know if it has anything to do with plus or not...but i just happen to know that this is a really helpful forum
