Well, I'd contact support first and foremost, but I know this sometimes happens if you use a IP from VPN that is marked as 'problematic.' For instance, if you use the free (albeit crappy) VPN built in Opera, it often does this, since the IP is shared by many people who also use the free VPN. If you're using a VPN, I'd try changing the location you're showing as and see if it still does this. Another possibility is that it's happening due to CB servers being all funky from development, as they seem to be doing today. However, I've only had this specific scenario happen with the free VPN in Opera.
