If you want to use isohunt then you should change your server to UK not USA or whatever its current location setting is.
USA server didn't work for awhile for isohunt, but these days it is working fine with the vee pee enn.
I have trouble going to prirate bay recently, not because of the firewall or my vee pee enn, but because of my McAffe's virus software. It won't let me get on it because it says it is a "dangerous sites that could harm my computer." But then again, how do I know? Maybe mcAffe is starting to do vigilante justice and blocking sites the company doesn't want you to go to. There is a work-around (A teeny tiny button that says, "go to site anyway,") but it just spins and spins and nothing actually loads.
