After Installing my second disc, Haven and Ragnarok fail to load every time. It goes to the loading screen, blacks out, and drops me at the main menu. Every other map works fine, as do campaign and Spartan Ops.
I have tried re-installing it twice now and am trying to borrow the second disc from my friend. I was unable to find a download on the XBL marketplace, so if that will fix it, I would greatly appreciate being told what to search for.
Thanks in advance.
