Did you assign Scan Lists to what you imported to the software? Remember that Scan List 1 is the default list for the scanner. Are there numbers showing on the screen? If not, you'll need to push the number buttons starting with the 1. What are you trying to scan and where?

Suggestion, plug the cable into the PC. The PC should start a search for drivers. Question, what cable are you using? If it has a stereo to mono adapter, take the adapter off.
What form of Windows are you using? If it is anything else than XP or 7, do a search on this site for how to install the drivers.
