the only reason to have the latest version is to convert from kn7000 format backwards to enable loading into your kn6000. If you are just converting from other manufacturers to technics there is nothing much gained in the latest version (apart from the newer model updates) and you can just save to kn5000 format and then load directly in your kn6000 normally, so there is no great need for the latest version in the first place since what you have will still work fine.
