there is this website that when i enter it in to my windows xp laptop it says it can't find it. and when i go to google and search it, it comes up but when i click it, it would't open. BUT the odd thing is that the website can be opened on my other computers. i don't have any website blockers or anything(it's not a porn site). can anyone help please?
