Troubles with nickname (Take a look please)
 

Hello,

My girlfriend just mentioned to me that she has already be seeing the same
nickname on msn for almost 6months..

I have Windows XP, she has Windows Vista (but that shouldn't be the problem,
all my other friends (with Vista) can see my up-to-date nick..

We both have Windows Live Messenger (last version)
Is there any known reason for this?
And my main question, can it be fixed? If yes, how?!

Thanks alot!
