E-mail problem

W8. In order to make my computer trusted I had the help of a tech support of MS gentleman. There was a problem with the password. I got my computer to be trusted under {removed} my old account was {removed}. When I try to enter in the new e-mail  e-mail account however it takes me to the old address. It prompts me   to enter a password for the old account. I enter the password I had for that account and it does not works.n, therefore I can not access my new e=mail. I have been trying to get help from Microsoft  and I have being in 5 different  departments and they keep sending me to another department until the last one told me that they do not have support for Hotmail and they told me that may account is free and therefore...? It is a Catch 22 situation. I think I am going to throw W8 away and go back to W7. I am  very frustrated.
