I played throughout the first disc of RAGE no problem, but when it told me to insert disc 2, a message came up saying "This game requires an update, but the update couldn't be found" I had both discs installed to the hard drive like it recommends, then i deleted disc 2 to see if that would help. Needles to say it did not, and now I can't continue any further in the game.
I installed the discs by using the normal install under My Games on the dashboard. The game told me to consult the manual on how to install but I rented it from Gamefly and do not have one. I was wondering if the game has its own custom install somewhere, but I couldn't find it. Regardless it shouldn't matter for this issue.
Any help is greatly appreciated.
Edit: My Xbox LIVE connection is working fine and is quite fast, no issues there.
