hi i recently bought this game installed it on my laptop then made a back up disk because the laser on my disk drive is realy bad if ther is any scratches it wont play,anyway i played the game for a few weeks with the original disk then stoped playing it for a while,then my laptop crashed and i had to re boot i tried to re install the game with the disk and it wud not read it, so now when i use the back up disk it starts to install but then a message pops up saying something about secure rom and the original disk.

whats the problem and can i fix it please help thanks.
