I am running into this issue as well. Any update?Si I've tried 3 different usb sticks format in fat32 and ntfs with no luck. I actually get a E4492 Cyber Security Access failure and E4423 Unknown reprogramming error 5 at step 0 error when attempting to program cluster with SPS2. I don't know if I can get a bin file from somewhere else to attempt the program as the cluster does recognize the usb when I plug one in but says no 22923964.bin found. I might have to call the acdelcotds helpdesk on Monday. I did turn off my antivirus and windows firewall with no luck. Thank you for the advise i've received so far.
