[magic_rose]

I downloaded a pc game (nancy drew), and i extracted it with winRAR, but i don't know how to open it using daemon tools. in the game's folder, there is cd1 and cd2, and when I start with cd1, it asks me for a file which is in cd2 and i don't know how to use it. it is rar file but i can't extract it becaouse it says : acceing denied...it is soooo confusing
can you please explane with details because i'm new in these things... thanx
