splinter cell chaos theory problem

[utd]

hi,

I have a problem making scct work.

I installed the game successfully and enterd the activatin code too.

then it prompt an error saying "insert the splinter cell chaos theory pc dvd into another drive then press retry"

I used dtools v.4.0.3he and mounted the mds image I've downloaded.

does anyone have a solution for this problem ?

any usefull posts will be appreciated.

ps:

I don't want any unpluging solutions.

I used sfclean to delete starforce driver installed by the game.

I used this method with pop3 and toca 3 and it worked perfectly, so I think it should work with scct but it didn't.
