I just purchased the game this weekend and I had the same problem when loading on my laptop. It would stop loading and crash when inserting the second disk. I took the disks to my desktop and they loaded just fine.
For my laptop, I looked up the properties of the CD/DVD drive, and disabled DLA (Drive Letter Access). After that, I was able to install the game completely and no longer crashed on the second disk.
I am however having a problem starting it on my laptop, so I am sure it is one of the driver issues. Game starts and I get the initial loading screen, then it stops, sits for about 2 minutes, and I get the old "Windows has encountered a serious error" dialog. I know everything works due to being able to install it and play it on my desktop, but I want to get it working on my laptop instead. Once I find out what is causing my new problems I will let everyone know in case others are having an issue like this as well. I read on one of the threads about the firmware of the drive, so I need to check that yet.
