Problem with IG2....!!!

[Theo09]

I have downloaded the NO-CD-File from GAMECOPYWORLD.
I copied the .exe into the game-directory and started the regsetup......
When I´ll start the game I´m asked to enter the cd-key.
I take the key of my original-CD but it´s denied....!!
In the info-file there´s no key for the NO-CD-File to be found...... :-(
I´ve tried to test it without the regsetup but it also doesn´t work..... :-(
Where I can get the right key needed for the NO-CD-File....????

Please help me......!!!!!
