If she has windows xp service pack 2
go to start run type cmd
ok that get black window
type netsh winsock reset
press enter
should get message saying successfully reset the winsock catalog you now need to restart your machine.
Reboot comp, a lot of the times this will fix the issue.
If service pack 1 you'll need a full winsock fix, the way to do it can be found on Microsoft.
