One question for those who have it. It says on the site that to update the software you have to register the unit. At one place it says "Registering a new FC-Datalogit is free." and right underneath it, it says "To register you must pay the US $20.00 registration fee, just click the "BUY NOW" link below after you have read the conditions." Can someone explain this to me? Is it free or do I have to pay? I think this is somewhat confusing.
