I have a HP Vista Home Premium 32 bit computer model m9000t. Use Internet Explorer 9. After several years of using Windows Mail suddenly my mail does not work. It keeps asking for User Name and Password even if the correct user name and password is entered. I called Charter. net three times. I have no problem getting my email when I log on to Charter. Each time I called Charter they check and said everything appears ok. The last thing they do is clear their database. Suddenly, my email shows up on Windows mail. This only happens once as they hang up and then when I go to check my mail its the same old thing. What is the user name and password. Charter referred me to Microsoft who then referred me to HP who then referred me to the $99.00 charge. any help will be appreciated
