I had this for a few years now and all of a sudden the computer tells me it can't find out PrecisionScan Pro 3.1. I have reinstalled the program and checked all the connections and nothing has changed. What can I do now?
In this case, you should probably try to re-install the driver for your scanner. You can find the driver on the CD that came with it, on the official web-page of the producer or you can try to use Google.
