As previously mentioned, AW recently had a purge of accounts without recent logins. You should have received an email (on whichever email address you've given them) warning you that your account had been deactivated, and telling you that you had a month to reactivate it before the deletion becomes permanent.
If your month isn't up yet, just go to the AW login page and click on "Reactivate me".
For the "stuck credits" problem, the cheap solution is to change your profile phone number to a phone registered in your name (not an unregistered punting phone) and with no porn-block. Then go through AW's verification process, spend your credits, and then remove the phone number from your profile.
