For some reason, I cannot download the latest title update for Halo 3 from Unity. It's litereally only serving me 1, while 3 is available. I tried downloadng a few of the other "version 3" TUs in the listing from the site, and none of them are working. My game version is at 1.2 with Title Update #1 installed. I just wanna play on Unity, can someone help me? Thanks
