?
Which error?
You mean the problem that I need to unplug all drives?
LOL illegal cd-key!
My friend, the message is: "Please insert the disc into another drive" or something. I think you got a wrong point
And if the cd-key would be illegal, why should it run with unpluged CD/DVD-Drives? (i've no idea about things like that.)
Sorry, I cannot see your logic...
