ut2004 Installation Help needed

[Bernd Dau]

Hi folks, specially hi Ryan!
I do own the DVD SE Version. I use Mandrake 9.2 so far.
As root I do cd /mnt <return>
bash scd0/linux-installer.sh --keep

It seem's to run but suddenly after a few seconds there apeares a dialog 
box that tells me :"Please mount the Unreal Tournament 2004 Play Disc CDROM
Choose Yes to retry, No to cancel"

But how? the disc is inserted... and btw. where is the copied 
install-script stuff?
