Rory.......when it happend to my 1480 with the binary cracked in the Health log, they asked to send it back for RMA after checking out the .ini files, because there is no counterfeit 1480 cards available. Apparently, there's a chipset on the card that wasn't functioning properly, SW recognizing it as a non-genuine Geo card causing that message.
The kind ppl at Geo support will RDT or VNC to the machine to check it out if you can send them a picture of the card to prove it's genuine...or with barcode number.
