This scanner has worked for several years on my old computer that was fried with a power failure spike. I have been able to download the favorites into the Proscan software so it seems the computer is communicating with the scanner but on the other hand I am not able to upload the favorites so the Proscan screen is the same as the Scanner screen and also I am not able to hear the scanner over my computer. I have disabled and re-enabled the IP several times in LAN settings. It seems like I am missing something simple. I have checked the port settings and everything seems ok. Any help would be appreciated. Thanks
