I have found the cause of the problem. Helicon doesn't like it if the stackshot cable is connected before Helicon "discovers" the camera.
The USB cable needs to be connected before the stackshot cable and it is fine.
Not intuitive, but might help someone in the future.

Cheers

Hi, I have also just received a Stackshot and am having problems with Helicon remote
Both the supplied demo and the latest beta 2.3.14.w
The software doesn't communicate with the camera at all
The initial software said No Camera Attached
The current Beta doesn't even say that
I am using a Canon 7D ...
