FIFA 2006 World Cup back-up installation

[maxass]

I made a back-up of my FIFA 2006 WC just in case. Now trying if it really works, I can't install it. The original DVD works properly, its simply the copy that says "Please insert CD/DVD in drive x:". Someone knows how to fix that problem?
Thanks in advance!
