I am hosting dedicated server for halo custom editions, and I was using Game Tracker to track them. I then started using a program called Gandanur (http://home.scarlet.be/mathy/gandanur/) which is a really great tool. It started working for about an hour, and then Game Tracker couldn't scan it anymore. My servers were up, and they weren't firewalled but it still wouldnt work. Now nobody can join my servers. Please help me
