Hello anyone who is reading this. So I have a serious problem and was wondering if anyone could offer me any advice or help. So my sister(16) and I(19) were playing halo reach and my sister had completed the weekly challenge last week right before I did and she received the 20,000 credits. Right after that game her and I both received this message that said, "Player is temporarily banned from earning credits." Not for a week or two weeks or permanently; just temporarily. We waited for like 4 days and we let our dad play on his account with us and it said the same message for him. Well, today we tried playing again and this time, my dad and I can earn credits now on my own xbox. On my dad's xbox we still can't earn credits. My sister is the only one who still can't earn credits because I assume she was the one who originally got banned? It never really told us a reason for being banned. We've never tried "boosting" or any other form of cheating and we always finish our games and never quit in between. Can anyone offer us some help? We've tried many things that we've read online but none of them seem to help. Any advice/help would be greatly appreciated. Feel free to add me on xbox to chat or anything.
