Is it that the SD card is not being registered (noticed) by the devices (it says the SD card there and plugged in when it is)? Or I it saying it is formatted/blank? Or is it just saying it can't read the files?

Most of them say they are free and/or have free trials, but to actually access any data it finds, then they may charge you a fee.
