I have read in the FAQs that a license can only be transferred between machines once every 30 days. That seems overly restrictive because a small, portable device is much more useful during the actual dry firing event and a device with a large display is much more useful for analysis of the collected data. I understand the one device at a time restriction in the license agreement. But I didn't see any mention of 30 day restriction in that agreement. I should be able to transfer the license at will as long as it is only used on one device at a time.
