Windows ME, Modem

I have a friend in Iowa I sent a Pentium 550 computer to, she finally got around to putting in a New US robotics modem, and cant get it to stay online, she has to use her old 95 machine, she tells me that the computer runs really slow and drops out after 10 minutes and says adjust your content advisor, Having only XP at home anymore I dont know how to tell her to fix it, although I thought the content advisor was a Security setting,

I told her that her ISP was having trouble with the computer as the modem does dial up and hook up to the ISP computer, any help you can give me I will pass along,

thanks
