I'm running Win10 (but also tried Win8). Downloaded the latest USB link software, it detects the ESC fine. But when I go to the "Firmware upgrade" screen, nothing is listed in the "Available versions" drop box. Same behaviour on both Win10 and Win8. I've tried disabling firewalls and anti virus, also tried compatibility mode for XP, no joy.

Any ideas? I'm struggling to find anything on Google.
