As A bonus I have also included the digital Juicer so you can download any torrent of digital Juice
You need to mount any downloaded content using daemon Tools or burn it to a disc
open up the digital Juicer software go to file install and it should recognise your disc image as long as it is mounted
it will ask you for the serial number for that content Just put in any email address and run the keygen provided in the crack folder.
Just make sure you are offline or blocked digital Juicer using your firewall
And do not upgrade digital Juicer so block upgrades as well.
