i have xbox live silver, i used it to download maps and gametypes from here. i have no problem loading gametypes, however i tried to load a map called bumper cars (created by CMNier, go get it) and this message appears with service tags blinking:
Unable to start because a member in your party cannot load user-created content
it does the same for theater and forge maps i created. and i didnt downlod videos yet. if i lload theater the same message appears
this happens for ODST as well
