forza horizon being reset

I played forza horizon a minute ago and when I came on I had no cars, cash, paint jobs nothing it’s like I’ve deleted the memory. However I check my HDD hard drive and I still have all of my dlc content, saves, photos. But when I start up its like I’m loading up a new game. And my xbox 360 is an old elite and has no internal memory so I don’t know what’s wrong somebody help me with the problem
