[TenTec] Orion 1 Upgrades

[John Chance-Read]

I've just aquired an Orion 1 upgraded to 2.062a.  I am deaf so dependent very much on the scope.
I tried upgrading to 2.063xg but although I have downloaded it into my computer OK,  there are no
directions as to how I get it into rig.  I have connected the Orion up to my computer as described in 
the manual.  It says "follow the instruction provided" and "send your new software over to the transceiver.
How ? as my computer doesn't recognise the transceiver.
Your help appreciateed
