@richars1 -
Do you use a shared or public computer, by chance?
Another thought is to attempt to change your cable IP address. here is an except I found online and that I have used in the past. It may work for you if you have the ability to follow it (take the time off you home pc):
"Most IP addresses given out by the Comcast DHCP system are in a leased mode.
This means that if your modem is turned off for several days or more, the IP address goes
back to a group of IP addresses to be automatically reassigned to other users."I would not try to use any type of "proxy" as most websites (including this one) do not approve of their use on their forums and, once its discovered, you will be BANNED. You'll want to avoid that, I'm sure, so I'd simply stay away from anything like that if you are trying to learn more in the net via similar forums.

If you are on a public PC... use another place to gain PC/net access (i'd even go as far as changing my passwords - no harm in that).
Swytch~~
