Okay, so I have this annoying problem, after that last update I haven't been able to use the XBL marketplace. There isn't any content! There is no content in the game or avatar marketplaces! I haven't checked the video or music marketplaces yet. Its really word too because I signed onto my brother's account and the content is all there! Has this happen to anyone or am I the only one? I'm getting really frustrated, I've been wanting to buy and download Dragon Age for a long time. Does anyone know what I should do to get my marketplace content back?
I would definitely suggest contacting Microsoft as soon as possible and letting them know of the problem. They will work through and help you figure it our pretty fast, and it will help them prevent it from happening to other people.
^This. The only thing I can think of is that you have parental controls on, and your brother doesn't. You should check just in case.
