"you may be getting this page due to someone's misuse of the site in your ip range"
Basically somebody has been banned and they use a range on the IP address to ensure they can't get back on rather than just one specific IP address. But it can cause problems for others.
I reckon you should reboot your computer and while thats rebooting, turn OFF your router for 3 minutes then turn it back on again.
Then see how you get on.
