My setup is I have 2 xboxes. One in my room and one in the living room. The living room is the 'main' xbox where I normally download my DLC but my profile and some DLC is on the thumb drive and not a hard drive so I can easily go back and forth.
I got excited and downloaded the minecraft skin pack in my room. I tried to redownload it and move it to my main xbox but it still won't let me play with the skins on my main xbox because it says its corrupt.
I have never had this problem before but I normally download stuff on the main xbox because it has a hard drive and the one in my room does not.
I even recovered my gamer tag on my main xbox and put the profile on the harddrive, redownloaded the DLC but it didn't work.
