I have tried to reset my windows live password three times. Microsoft confirms the change and it works on my pc with vista but not on my laptop with windows 7

I was unable to sign on to windows mail on my pc or windows live on my laptop. This all started about a week ago after a server problem. I received a password that worked on my pc using vista but it would not open on my laptop using windows 7. I have tried to reset it three time and I get a confirmation email on my pc with vista but I still can not sign on to my laptop with windows 7, it is very frustrating as I am going to be traveling and I need it.
