Problème when running gamecube game on dulphin emulator

[AirborneCody]

Hi every one! I'm new in emulation gamecbue! I would like to play to gamecube game on my pc(i don't have any wii or gamecube, it's dead) ! I browse the game i want to load with the emulator: Star Wars Rogue Leader
and when I double click on the game, it launches the emulator(dos windowà but i have this message!


and the emulator crashes
And also when i click on Play on the emulator, I have this other message:


emulator crashes after too!

i think I must dump like the tutorial says in the forum with rawdump 2.1, but it doesn't work(i use daemon tool to insert the ISO, my original dvd is broken, so I had to download the game)
here the message error I have when I try to dump the gamecube game:



it's the same error for the 3 drives.

How can I dump correctly, if it is the solution to launch gamecuube games with the emulator, or did I forget anything?

sorry for my english, i'm french
