From sse:
I have received the configuration - the problem is now clear:
Daniel has two AbelCam Pro keys and no camera license.
Both keys were entered correctly in the camera license entry field,
but as they are not camera keys they were not accepted for the 2nd camera.
I thank you all so much! I am leaving in a few days and needed that second camera badly. I remember my confusion over the license for software and licenses for cameras when I made my fist purchase.
I'll be using the second software license at my cottage, so no money was wasted.
I've seldom been provided with such competent help from other forums over the years...very impressive software and equally important support when I needed it.
