Whenever my friend tries to invade me, he says my name is grayed out and when he clicks on it it claims that I'm not available. When I click tail or hack the same friend who was trying to do the same to me, it gives me an error that says I haven't completed the They Can't Hide mission. Could someone please help me with this, we have tried reinstalling the game on both of our clients, and disabling firewalls. We suspected if I deleted my save it would fix it, but neither of us want to do that.
