Okay, try to follow me here. At my home, I don't have broadband internet (literally doesn't come to my house), so no online stuff. But I do have a gold account so I can bring my Xbox to my Bro's house ever so often and play online, buy content/arcade games etc. I re-did my license after I got a new hard drive this past holiday season. So all my downloaded content has worked fine.
Usually as I said above I would take my Xbox over to my Bro's to play. Instead of doing that, I just moved my profile (This one, actually) on a re-formated USB drive, went over there, moved it on to an extra console he had laying around and played while I visited a couple of days. Good stuff since I had a pass for GOW 3 beta! until I came back home and moved it back on to my console. Now my DLC doesn't work for my games, but I can play my arcade titles for some reason.
What did I do wrong? My Bro and Nephew convinced me I would be fine moving my profile. It seems like I messed up my license or something. Can anyone tell me how to fix this so I play my downloaded game content offline again. Thanks for reading this lengthy post.
