Thank you very much ! I don't know mkkhan but I thank him very much, it is also the only DLC that I needed to complete all the downloadable content of WWE games for XBOX 360! I really thank you very much.
For those who cannot make it work, it is because by default they are blocked, they need the XM360 application to unlock it. Here I leave the two cases that can be presented:
1. If this is your first time installing the DLCs just run XM360 and unlock the DLCs that will do.
2. If you already have the game and DLC installed, delete all of them and copy these new ones. Also, reinstall XM360, as it has a bug that shows unlocked DLCs when they aren't, so I recommend reinstalling to unlock them again. Once that is done the DLC should work including Bret Hart!
