Ok BountyWarrior, I just phoned them up and they claim the block isn't from their end and that they don't have a policy of blocking sites.
They claim it must be the site that has blocked a certain range of ip addresses and that the best thing would be to leave the modem off for 24 hours to get a new ip address. They claimed not to be able to forcibly assign me a new one.
Is there any way you can contact gamecopyworld admins to see if our ips have been blocked?
I felt a bit of an idiot telling them the site name but it wasn't too bad.
