Did you set the correct Comm port? When I was setting this up after I downloaded The WIn97 program I could not upload my data from the scanner. I found the USB Serial Converter in the Device Manager location and clicked on it. I then got the properties window and clicked on troubleshoot button which reinstalled the driver. After this was done, I noticed that next to the text USB Serial Converter in the Device Manager directorary, the port name was listed (com4).
I then opened the Win97 software and selected Configuration from the top tool bar. Once open, I selected Serial Port and selected 4 for the Comm port location this caused everything to run correctly.
If that doesn't work, I would contact Radio Shack at
www.radioshack.com and click on the "Contact Us Anytime" link located at the bottom of the page under the heading "Need Assistance?"
They are quick at replying. I hope that you get this up and running.
