Error changing profile email address

I tried changing my email address by clicking the "Change email address" link under the email address on my profile page. I got the error message: "Unhandled Error: 151002092631125.ord-prod-app4".

I received an email at the new email address I entered, asking me to "activate my account". I clicked on the link in the email. It brings me to my account and my old email address still shows up on my profile page. I tried logging off and could only log on with my old email address. The new email address does not work.

Please help.
