Just to make things clearer, there was a paper voucher included to the 5 disc box set which said:
"thank you for purchasing the 20th anniversary edition of dubnobasswithmyheadman. [-code-] please go to
www.underworldlive.com/redeem to pick up your hd download of the 2014 remaster of the original album".
That's what I did in October and I downloaded a very large zip file including 96khrz WAV files of the full album. Only the track "Cowgirl" is incomplete and I can't try to re-download the zip file as I have used my code before. All I am looking for now is the full 96khrz WAV of Cowgirl. Cheers...
