Thanks for the quick reply Kevin.
I didn't have HC-Sim running, nor the HC-2 plugged in, nor the CI-1 plugged in.
I uninstalled RPA and reloaded it. Again, with nothing else plugged in or running, when RPA came up it again showed the USB Connected. And if I try downloading from the HC2, it eventually tells me that it can't connect to the internet. I know I'm connected to the internet, as I am on the same computer looking at and replying to this user group.
Tis a puzzlement.
