I'm having the same issue - the cusadmin login is not working. I've rebooted the router and that didn't change anything.
What you have sounds like what happened to many of us in May, when Comcast first forced the faulty 188.8.131.52.1 firmware to the SMCD3G-CCR, and then had to revert to the older 184.108.40.206.7-CCR firmware. After the 220.127.116.11.7-CCR firmware was reloaded, many users could no longer use the cusadmin account. The fix was to call support at 800-391-3000 and have a business class tech either rebuild your profile or reset the cusadmin password. If you have a dynamic IP address account, you can probably just do a pushbutton factory default reset on your SMCD3G-CCR (but if you have any port forwarding rules setup, you will lose those with a factory default reset).
