Not Receiving Email Authentication code / Hacked

Yesterday I donated 150euros on My Alt account. Liked Every other day Today i tried logging in my account it asked for authentication code. Like always I Opened my Email and I Received no Code or any email from warmane. I Am trying to send the code for past 2 hours and its not working.
I am Worried that Someone hacked my account and changed Email (even though password is still same) or Its just an error that i am not receiving any Email.
Please let me know if this is possible and What can i do now ? since i cant log in on website or In-game without code. Is there a way to login.

If someone had changed your accounts email address, you would have received an email about it. The email most likely just isn't arriving. You can disable 2FA here but it also involves receiving an email so it also might not work. It's most likely temporary issues with emails. If it doesn't start working soon, you can send an email to [email protected] for support.

Actually I Changed my Email couple days ago.. since the account was inactive and i forgot my old Email. I changed the email and Started 2 factor authentication 2 days back and was receiving codes on New Email.. Today while logging in i got message - "Due to logging in from different address you account has been temporary locked and Code has been sent to your registered email address". I should received the code on my New Email right ?? I hope the code isnt sent to Old email due to some system error.

Code should be sent to your new email address.
