I have purchased csi dark motives for the nintendo ds on two seperate occasions and have also referred to several walkthroughs relating to the game and cannot lift a fingerprint from an envelope on the first case. I have written to nintendo who replied almost immediately saying i have to get in touch with yourselves, which i have done about a month ago but have not yet recieved a reply. I would appreciate either confirmation that there is a fault with game and would also like to know where i can purchase the game without the fault. As you can imagine it is very frustrating as it is the first case. I have the csi game for the wii and have completed it and would love to do the same with the ds version
