Changing my login email

So I got a new email (the old one kept getting hacked) and I'm changing all of my login emails on all the sites I use to the new one. And I'm having issues doing it here.

If I go under my account > personal > and try to change the email, it just tells me "Invalid Email"

Do I have to email el_tino or..?

It has just let me change mine. Did it prompt you for password after making changes?

Don't do that, otherwise I won't be able to hack you!

Only thing I can think of is what it said: invalid. Which might mean it doesn't have an @ symbol or a .com address or something similar.

If you are absolutely sure it is valid and typed correctly, email Tino.

PM me the email and I'll check into it.
