I am sorry to pull the n00b card, but I am trying to get the disc swap to work with Halo 4 and am experiencing this exact problem. Any guidence you can share as to my next steps would be greatly appreciated. So far, I have tried the step belows:
Used F3's (version 775) File Manager to copy the HDD1:GamesxBox360Halo4Disc 2Content00000000000000004D530919 to HDD1:Content00000000000000004D530919
Used XeMenu to delete the HDD1:FreeStyleData folder making sure that the data would reload.
Rebooted the xBox
Reset the HTTP username and password to what I liked.
Logged in and the problem remained.
I see both games in F3 when I look under xBox 360 games. I must be missing a step, but not sure what else to do. Any help would be greatly apprecaited.
Thanks. Slope
