Changing e-mail address associated with my daughter's account

Hi,

My daughter's khan account was created for her through the school and is associated with her school e-mail address.  We moved and she no longer has access to that e-mail address that was used to create the account.

I tried to change the e-mail address on her profile, but it wanted me to put in a password.  In order to save the password it also wants me to log in through clever, which she no longer has access to.

I'm listed on her account as a teacher/coach as well... so just trying to disassociate the prior e-mail address and set up a password so that she can log in easily in the future.

She hasn't logged off the website in awhile, so she still seems to have access, but the moment she logs off, she will not be able to log back in.

Please help!
