Welcome to CHF goobay!
You should have post this in the software forum.
But I'll try to help you here.
You OS is incorrect.(There are only 2 SP out there)
Go to start -> run and type "winver"
There you will see the correct OS. (I think it will be XP (home/professional) SP2.)
Did you try to update you CD-driver?
Go to start -> run and type "devmgmt.msc" this will get you to the device manager.
Go to Disk drives, right click at your disk drive and click update.
Let us know if it worked.
