Yes, I had the same problem. Have you updated an Evercade handheld or Atari Gamestation Pro on the same computer? If so, I believe that is the problem. I finally was able to update on a laptop that I had not used to update any other system. I think the Atari 2600+ is using the driver provided for the other systems unsuccessfully. I have not figured out how to get the driver changed so the Atari uses the right one. If you have access to another PC that was not used to update another console, I would try that first.
