Error on 99% examine game data on LOTRO

The game i am talking a about is Lord of the Rings Online and i got a way to avoid re install the game when it stops on 99% on examine game data. To fix this you must go to your game folder and then copy all files on "Patches" folder to your game folder and then run the client. So if your game is instaled on C:\\LOTRO\ you need to copy all files from C:\\Lotro\Patches\ to C:\\LOTRO\  . You might have to do this more than one time and then it will be able to update again and you will be able to play again :). I hope i helped.
