When i try to log on to windows live messenger an error message comes up that says "we were unable to sign you on to windows live messenger. possibly because of a problem with your service or internet connection. Please make sure you are connected to the internet." Then it has an error code that says 81000306 Then there is a button for troubleshooting. I have everything besides something called key ports. If i didn't i wouldn't be writing right now. I know it is definetly not the computer because MSN has worked before. Does anyone know how to fix this?
