Sorry to be cross posting since my other post is a bit off topic and there's a bigger argument going on there, here it is:
Roberto has published the decrypting key here (http://www.hydrogenaudio.org/forums/index.php?showtopic=19190&st=150&).
Which software do I use to decrypt my *.erf files?
schnoflers abchr can decrypt them
Load ABC/HR Java -> Tools -> Decrypt Test Results
Missed that completely.
Should have posted earlier, but I couldn't reach the site.
By the way, a bloody big surprise my results!
