maybe try skip error and take another virtual drive (alcohol, d-tools, clonecd, gamejack5)
if that doesn't work I dunno what u can do. Maybe then the reason is ur DVD drive(2old 2dusty whatever). this is all I can say cuz the release in germany is on friday.
But if installation is ur only problem u could try 2copy all files from DVD 2 a folder on ur HDD and instal it from there
