Fuji Host Interface vs. FujiFlexa User Host Interface (Fuji NXT) -- Hi, wondering if anyone knows what is the difference between the Fuji Host Interface and the FujiFlexa User Host Interface. We are trying to purchase the Host Interface v6.28 in order to pull data from the NXT machine into our system but the Fuji reseller in China is telling us that the Host Interface does not exist and that what we need is the FujiFlexa User Host Interface (which I have never heard of and a google search finds nothing...). Any help is greatly appreciated - thanks.-Helena
