Unable to access Enom account

A couple of my domain names registered with EnomCentral.com are expiring soon, so I thought I better transfer them to Go Daddy while I can (Go Daddy being cheaper than EnomCentral). I logged onto my EnomCentral account to unlock the domains and retrieve the authorization/EPP code. However, when the familiar EnomCentral dashboard appeared, it “ERROR – Account not found in database.”
