Problems running games on RGH with FreeStyle 2.2

I have a Xbox360 slim with RGH and the Freestyle 2.2. So far it has worked beautifully. I have an internal disk to step and convert the ISO’s with ISO2GOD. It happens from one moment to the next, all the games that put the XBOX via ISO2GOD or through the Horizon with a pen drive, always gives me the same error: error game, the game couldn’t not start. Try downloading … "when I try to run. However, games that were already there, they run perfectly …
I tried to upgrade to the FSB 2.2 to 3.0, but is eternally in part: “preparing update info”

Someone who can help me?
Thank U!
