This is the fix I got from NCH tech... I'm on a Mac, but maybe it'll work on a PC.
Try the following:
Uninstall the version you currently have on your PC
Then restart the computer
Download the software again at http://www.nch.com.au/scribe/index.html
Then re-enter in the ID Key information
This worked for me for a while, but before long, the foot pedal started dropping in and out again, and now the software can't find it at all. I have an approved foot pedal, the Alto Edge Infinity, and I've bought the "professional" version of the software, but the foot pedal installation wizard can never find the pedal, no matter whether I swap ports or reinstall the software. This programme seems to get worse with every upgrade...
