Gmail not valid

On SWTOR I changed my registered email to Gmail, but on Origin, it won't let me change it to my Gmail because it says it is an invalid email, it's not. Also before this on SWTOR I had no problem getting email on Gmail to verify my account, now I have been waiting for over an hour and still no email. Called customer support, literally did nothing other than verify it was my account, still sent me a verify email that never came and wouldn't let me log on. I'd get a SWTOR security key but I need to be able to log in first.
