The block may not be on your account but instead on your IP Address. For some reason this used to happen more regularly, but it still affects some users. Whomever you spoke to in Support may not have made this connection.

Users who connect from dynamic IP address ranges are prone to being mistaken for each other when they are given recycled addresses (which, nowadays, is every IP address). This is especially likely if you were previously able to log in without a problem.

Try unplugging your router from the AC Mains (disabling power) for about 5 minutes, then reconnecting. You should be given a new IP address from your ISP, and this may not be blocked. Once reconnected to the Internet, try logging in again.

re:  Your update.  DON'T leave your firewall turned off.  You should always use both a software firewall (Windows firewall, or one provided by a third party like your antivirus software) and the NAT hardware firewall built into your internet modem or router.  Turning them off briefly to troubleshoot a problem is one thing, but they should never be permanently disabled.
