OK, I can't actually see the GUI settings scheenshot so I'll have to take your word that you've got the Program field setup to point at the sacd_extract.exe file, and you had overwritten what came prepopulated in that field.By the way, I am now getting that the 2002 port is accessible, but getting the message that it can't open for reading.
In terms of the flash drive, that looks good, but if you had previously done any clicking around inside of the files in that folder it is possible the script was broken, as any stray keystroke there will break it.
If you know you didn't click anything in those files it should be fine, but if you think there is any chance that something might have accidentally been altered there, just delete that AutoScript folder from both the flash drive and your downloads folder too and download a new one. Place an unzipped AutoScript folder at the root of the flash drive and don't bother clicking into any of the files on it, as there is nothing to see or change there.
With regard to the flash drive itself, there is an unexplained phenomenon with certain drives being incompatible, likely because they have a hidden primary partition. Some members achieve success merely by substituting a different USB flash drive, and preferably one that was never previously reformatted using the Windows Disk Manager.
Most any low capacity (<64GB) flash drive will come straight from the factory/packaging formatted FAT32 with a Master Boot Record partition scheme, and that will work, as would NTFS format with MBR. What won't work with a Sony player is exFAT, and some larger capacity flash drives (>64GB) sometimes come factory formatted that way.
Lastly, sometimes after repeated early failures, the only thing you actually need to do is clear the deck with a hard power cycle. Remove/replace the AC cord (with flash drive removed), allow the unit to go through it's reboot sequence after replacing the AC cord, and once the display goes dark, turn the Power back ON, and try again using the steps previously outlined.
