Harry Potter PC game

[PhyruZ]

I've got the Harry Potter PC game of EA Games.
I've also got the registration code, but when I try to start the
game, I get the following error:
"Please insert the correct CD-ROM, select OK and restart application"
Does anyone has this problem too, when yes, can someone
help me with this, so I can play the game.

thx
