Halo 2 Vista help.

I come to you guys in the last chance effort to get H2V working properly.

I can install the game fine, and run the game perfectly. It’s just that I can’t connect to games with more than one person in it. It says that something went wrong, sorry about that!

When I connect to a lonely guy looking for a match, I can play fine, but as soon as someone else comes in, I get disconnected from the game, which is infuriating since I bought the copy legitimately.

I can only hope someone knowledgeable here knows what the issue is, and can help me.

My specs are;

OS: Windows 8
CPU: AMD FX-6300 6 Core 3.5GHz
RAM: 8GB
Direct-X: 11

And before anyone suggests port forwarding, I’ve opened all the relevant ports.

Double check all of your fire wall settings on your PC’s Fire Wall, your router, and/or your modem, sometimes (I know you said you’ve done this) your router/modem will have firewalls that can cause issues like that.

Double checked all my firewall settings, everything is open for Halo 2 Vista.
