So my Xbox had an E74 error a couple of weeks back, and today I got it back... or so I thought. It turns out my Xbox must have died a spectacular death, Microsoft have sent me a brand new Xbox... Which leads to my problem. All my old XBL material, all the game add ons don't work properly. If I'm logged in XBOX Live with my gamertag there is no problem, it knows its me and all the games are unlocked. However, if I sign out or use another profile all the XBL games are trial versions. It used to be on my old Xbox360 that any profile could work with any XBL game that I had paid for. Some game content also didn't work properly, SF4 costume packs didn't work. Anyway, I've done what the Microsoft site suggested, and gone to my download history and redownloaded EVERYTHING. This took a while and I assumed that this would update my licence agreements or update my serial number registry, but the same problem persists. The problem is if there is any problem with XBOXLive or my internet, all the XBL games and content WON'T WORK. How can I fix this? Cuz its annoying me. Help please?
