Can't sign to my msn messenger!

Hello,

My problem is that when I try to sign to my live messenger, it says , "incorrect password'.

Since then I changer the password but it still won't let me in. It says you are not connected to

Interent. I've gone to to control panel ,etc but still it won't let me in ! This is getting ridiculous

that I can't get in my own messenger. I, have tried different things over the past week.

Please tell me how to remedy this situation. It is very frustrating.

Thanks, David
