How Do I Change My E-mail address??

Hover your mouse over the home icon near the top right of the screen. When the menu comes up, choose profile. That brings up your profile info, and you can change your email address from there (about the 5th item down)

Actually it's even faster to get to if you just click your user name near the top right of the screen

I just tried it, and it worked for me. Sorry if this is what you tried before, but just to be clear:

Click  on you user name near the top right

That takes you to the edit profile page, where you should be able to click on "change email" next to your current email address

That will take you to a screen that looks like this:

Enter the information, and click change email. That will send you to your profile page. At the top of the screen there will be a message that says you have to click a link in an email sent to the address you just entered to verify it. Go to your inbox, click the link, and your email address will be updated.

If that doesn't work, email support: https://support.chess.com/customer/portal/emails/new
