MSN Dial Up Commection Problems

I Need Help But I am not sure if I am in the right discussion Group.
I already have MSN & with a new PC with MSN Dial Up Set Up I am given two
numbers as a local connect. My Area Code is 573 & My Prefix is 783. I am
given the following two numbers 573-561-1004 (which is not a good #) & next I
am given 573-783-3001 (Which is a good #).....I have two problems & the first
is I cant uncheck the bad # because I am instructed to choose more than one
number, So I tried to connect manually with the good connection number & I am
told my MSN User name and/or password is not correct.... I have rechecked for
any typos on my user or pass & I know for sure I am correct? So if at all
anyone can help me I would greatly appreciate the Help Well in Advance.
