Sometimes when I try to host a game, I get a error message in the Options and Messages box. I want to host games, but theres only 2 I found that I can host. The rest I tried, didn't work. I must have tried over 50 games, and it wont let me. It only happens to my IP, i logged into a different key on my computer, didn't work. I logged into this key at my friends house, it let me host everything. I really want to know whats happening. (P.S. This happened before I got a router too)
