There have been pirated copies of K31 files popping up on and off various vola rooms. Don't feel ripped off though as this time the 'tist is not to blame for the dead links.
YT banned K just recently and removed all of the files. Thus making the links dead. K will probably be reupping somewhere else soon and will inform the paying customers where. You just had the terrible luck of buying in to a 'tist at just the wrong time.
