Thank you for taking the time to read this. I recently bought Borderlands 2 and I wanted to play online with some friends. However, for some reason, even though I have downloaded and re-downloaded the 'Compatibility Pack' at least 8 times, the game still does not register that I have it installed. I am not sure what is causing this problem, but I had someone over my house the other day, and in order to make my Xbox run faster, he deleted the cache in my system. I suspect this is the source of the problem. If there is anything someone could recommend doing to fix this issue I would appreciate it. If there is any more information on the subject you need to help, just ask. Thank you for your time!
