Ok....so I received the answer to my last question and realize now that I should have recovered my account onto my kids xbox and then purchased/downloaded the new COD Black Ops map pack which would give them access to them on that console and then once I recovered my account back onto my console upstairs I also would have access to the maps.
Since I did not do that I was simply going to purchase the maps a second time under my kids gamertag but his gamertag does not have authorization for purchases so I am stuck again. If I log in under my gamertag it will allow me to download the map pack again to the console but I have already copied the maps to the console and they won't work when my son is logged in under his account.
Not sure what else to do here....I am trying to download them now as maybe that will be different than copying them with the flash drive but any additional help or guidance is appreciated.
Thanks!
