MM won't talk to CastleLink

[fastbaja5b]

Hey guys, I have an older MM ESC I am using in my drifter project, went to update the settings via Castle Link and it won't recognise it. I have tried the driver install support page and how to try and re-install the driver through device manager but no joy even after reinstalling Castlelink itself.

Latest version Castle Link and computer is running Windows 7 64 Bit.

I was looking at a Field Card anyway, if I got that, could I update the MM and the MM Pro in my SC8e using that and use castlelink through the card on both or would the MM still want to use it's own USB port?
