Microsoft Train Simulator Protection?

[Fender]

it works?
i've purchased Train Sim from Canada;

i've used "copy cd" in NERO 5.0.3.8 (as usual) and it mades the 2 images by the virtual recoder;then i switch to the YAMAHA;finally burns;
after burning, i tried the installation:
cd 1 works fine, just cd 2 at 27% (about), says:"media file not verified, installation aborted";

any idea?

thanx guy

ciao!
