Installation CD Problems

Today I received the EFILive Flashscan program and I'm currently trying to install the software on my laptop. I'm following the document "Installing Flashscan on WinXP" on EFILive's website. I can get up to Step 5 which states "Select the folder that contains drivers for your hardware". I can't complete that step because for some reason my laptop doesn't read the installation CD. The CD-ROM on my laptop will read everything else I put into it except the installation CD. What is going on here? Did I miss something? Any help is appreciated.
