Syberia: Having problems with a scratched CD

[Netslider]

Already had contacted Microids before posting this thread, they told me to send them the scratched CD and they would send another to replace the damaged one, but I would have to pay for it, in the end it would be cheaper to buy a new game. But I don't want to spend another €50(that's how much a game costs here in Portugal).
And how can this Toothpaste guy help me out with my scratched CD? Anyway, I'm giving it a try.
