Hello All, A few weewks ago I purchased a RS pro 668. I followed the instructions and from the sd card loaded both the software and drivers onto My computer. Then the mishap, I accidently formatted the wrong sd card, the one that came with the scanner, and lost My ability to load the software and drivers onto a second computere, I like redundancy ( - : Since radio shack does not offer any support any more, or none that I could find on their site, I went down to the local RS and asked if I could use one of their for sale new scanners, which by the way were on sale at $250 and load from there the software and drivers off a new scanner sd card. They said ok and all went well until I got home and tried upload from My scanner to the new installed software. The scanner would not communicate. Driver problem? I am not sure. is there any place I can go to, to download possibly the sofware again and also the drivers. My usb cable works on My first computer, but not the second one. So I am not completly lost, but would like to get the other computer to commuicate with the scanner. Thanks, for any and all help on this matter. Bob C
