I can do both. I don't like MSN, but that came with the DSL service, so I'm stuck with it. Also be aware that MSN gives out you phone number to marketing people. There is a way to disable from doing this if you haven't already done it.
It should just be a temporty thing with your account. How long has it been out? If its been out just today, tommorow it'll probably be alright. I've had it once before, and worked the next day.
