The photo appears to be a Pro-668. Bigjosh, it that right? You have lost the CPU firmware.Easier to Read Pro-18 Digital Scanner and iScan Software Manual
The OP's photo says Radio Shack on the scanner. Let's let the OP tell us which scanner it is before loading the wrong firmware and bricking the scanner. I believe it is a Pro-668. The Pro-18 does not have the MENU button shown in the OP's photo.you need to reinstall the firmware for that scanner which looks like the grecom psr-800.
If I remember correctly, the latest version is 2.5. The Legacy Upgrade would make your life a lot easier and improve scanner performance at the same time. You would be able to use WS1080/WS1088 EZ Scan for all future updates.You need version 2.3 or 2.4 pro-668 firmware.
