Hello. I use MSN/Messenger, and I can never seem to sign in. For the past few days, whenever I try to sign on, a message informs me that "either the network is busy, or I am not connected to the Internet", when I am absolutely certain that I am indeed connected to the Internet. I know that I am using the correct e-mail address and password, since I have being doing so for the past year or so now. Does anyone know exactly how I can solve this problem? I was told about a "firewall" possibly interfering with the connection, but have no idea how to go about disabling or working around that. I appreciate any and all help that any of you may provide, and I am sorry for wasting your time. Keep in mind, I am only sixteen years old, know virtually nothing about computers, so...please try to work with me, as I will try my best to understand. Thank you!
