I have a suspicion it’s linked to your email account. We’ve been having issues galore with any of the Microsoft email services, like Hotmail, Outlook, and Live.com. I’m sure you’ve whitelisted AFF all over the place, with Windows, your anti-virus/malware, your browser of choice, and so on. The usual fixes, like clearing cookies and browser histories, don’t seem to fix this, either. I’m hoping DG can come up with a solution to this, because it’s really, really frustrating for anyone using those email services.
PM me if you want to talk privately, and perhaps we can change your email account of record, even temporarily, so you can reset your password.
