hey guys

ive been using msn messenger for almost a yr and i recently started to use adium a bit more frequently.
this problem came up today and i'm not sure how to fix it.
everytime i sign on msn messenger my display name becomes my email address, no matter how many times i change it, it automatically defaults to my email address each time i sign on.
the same thing is happening to adium also.

any idea how to fix it (other than never sign off again)?

thank you
