trying to change my email address

I am trying to change my email address you have on record. I go there, put in my password, change the email address and confirm it. Then I press SAVE CHANGES and am told my password entry does not match the password you have on record. THE PASSWORD I ENTERED IS THE SAME AS THE PASSWORD I SIGNED INTO THE FORUM WITH TWO MINUTES EARLIER! I tried several times to be sure.

Any ideas? Thank you,
