I have a Pro-164 and I'm using ARC 300, I plug in the scanner and hit download, and on the scanner's screen it completes stating it has finished while in ARC 300 it reaches and gets stuck at what looks like 85-90%, at which nothing happens afterwards. I let it sit for about 10-15 minutes to see if it would do anything but it never finishes downloading. My 164 is on CPU ver. 1.04 if that helps. Is there something I'm missing?
