LinuxQuestions.org - An error occurred during the Installation

I wanted to install SuSE Professional 9.1 but I faced an error!

I used the "Manual Installation" option; then I wait and then I chose "Langiage" and "Keyboard Map".
It did some processes and wrote "Starting yast" and doing some processes again,

and then showed a graphical page for a moment that I think it had two buttons: "Accept" and "Abort". but I couldn't select anyone because of appearing a red error window :
"An error occurred during the Installation!"
and it only had an "OK" button and when I hit OK it returned to install options!

Before hitting OK, I tried "Alt+F keys" and on "Alt+F4" I saw this message on the page:

"... (none) kernel :cdrom: open failed "

Somebody said me that it may that the problem is my CD-Rom but Before installation, in installation options I chose "System Information" and then "HardDisk and CD-ROM" that I saw my CD-Rom is detected and I saw its model in that window.

My CD-Rom model is: ASUS CD-S400/A (40Xmax)

I am also using Knoppix 3.4 and none of my hardwares have problem with it but my WINMODEM!!

Do you think that the problem is the CD?! (I bought it not downloaded and burned)
Do you think newer versions of SuSE can help me?!

Any suggestion is welcomed :)

UPDATE : I've used the mentioned CD on another system and I faced that error again.
