Purp - but you aren't even reaching
the forum, apparently. Your problem, as you describe it, seems to be that you are still on the home page trying to get
to the forum, by clicking a link
to the forum, but you don't get there. The home page still displays. (I took a look at the home page, and it does not appear to be part of the forum.)
When I go to the home page and click on the forum
link, I am immediately taken to the forum.
What happens if you click on this link to the forum, right here.
Do you arrive at the forum from that link?
How is your computer connected to the internet? You say you have another computer in the house. Who configured the things so that 2 or more computers can connect to the internet? Usually there is a router with NAT and a firewall. Did someone other than yourself configure the firewall? What about your computer? Does anyone other than yourself use it? Does it have a firewall configured, or software to secure your computer from spyware?
