installation problem

Hello!
I'm from Poland so please forgive me any language mistakes below

I have a problem with installation. The problem concerns CD 2. When installation progress reaches copying Routes (USA1, USA2, EUROPE1, etc.), a message like this appears: "failed to verify media. installation canceled". Does anyone know what it means? I am sure there is something with CD 2, I tried to download some patches or cracks, but nothing worked so far at all... Please help!

And other thing. I would like to compare my CD 2 with somebody else's. Could you send one to www.megaupload.com? The only matter is to divide .iso (it'll be most welcome ) image into 200mb pieces. (I believe it would be 3 of'em).

So, thank you for the answers,
greetings from Poland
Nexen.
