a problem with chankast

Hello! Can I ask you a question? Well I've got the Sonic Adventure 2 for DC, I've mounted it to Daemon Tools, got BIOS for chankast and flash too, but when the emulator starts I can't run the game, because when I set the right drive in the emulator adn clicks on start it just says:please insert game disc.
What should I do? I really want this game. I've just finished the Adventure DX, but thats for PC :p
