NBA2K9 master solution!

2 days ago I installed a patch I forgot to back up the Slam Dunk later I now have to delete a folder, and from the new extract, after running the game but a lot of teams do not ask the master head is blank how can we return to the original players in the state that is not installed before the patch looks like Slam Dunk and so very eager to give an answer online extra points

re-install should be able to resolve

folder can undo?

If you can do not have to re-install it in trouble

re-install 2K9
