I just recently started playing the version that is on the Game Pass and the friends that I have been playing it with have told me that it has gone through some different versions and changes. I wonder if your issue is because of these changes that you
are having to buy a newer/different version from what you had previously. Not sure if this is what is going on, but I wanted to throw out some perspective since I had heard this from some long time players. Good luck, I hope that you are able to get back
to the game without having to pay for it again.

^^^This is the only way to acquire old purchases, and must be done from the original purchaser's account. It is archaic and slow and I hate it too, but it is still far superior to the system utilized on the PS3. It's about 10x slower and more buggy. Count
your blessing my friend that you are doing it on a 360!

If you do not see your purchase in your DL history, then the bad news is that you have no other options. Support will tell you that they only cover it for x amount of time and that after that, the licensing agreement ends and you must purchase a new one. I
found that out the hard way with content I bought for KoToR that I could no longer get back. ---AND that was back before the Xbox One was even good and off the ground, still during 360's heyday. Hate to be the bearer of bad news, but its true. Sad but true.
I miss my KoToR DLC. I also miss The Simpsons ARCADE game I lost the purchasing account to and never repurchased out of stubborness and now I dont have the option to. Bah! I hate licensing.

hello does this work for forza too you think?

I have uninstalled the game, which it is now re-installing.
