According to PWE support, the only way to trigger it to resend is to try logging in again. You can also disable Account Guard via the Create/Manage Subscriptions page... but you need the authorization code to access that page.
I know my email works fine. In fact, I've tested my email to be absolutely certain the problem isn't on my end. I can send and receive just fine unless it's coming from PWE. This would suggest (to me at least) that there is something wrong with their system.
I guess the only thing we can do is wait because the solution PWE support gave me still requires the code.
the problem is random, I have 3 accounts and two are having this issue the other got the code with no problem within seconds but the account that didnt get it has my lvl 50 so hope to fix it i hate to start over
