SDC2130 firmware update error

Hello, I am trying to update the firmware of our SDC2130's. (SDC2130 rev15, SN:F0227). Connected to PC, newest Roborun connected to COM port (via USB-COM converter). Via Úpdate controller via COM port' entering the desired data in the new window. Next error report:

Checking file: C:\Users\gebruiker\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.IE5\DG064OZJ\SDC21XX-Firmware-Update-v14b-033115[2].bin
Passed.

Searching for device...
Checking COM4...device not found.
Checking COM3...device not found.
Checking COM8...device found.

Controller found on COM8.
Resetting the controller...done.
Waiting for device restart...error.
Device starting string not detected.

Seems device is not restarting in the correct mode to receive new firmware.

What can I do?

I tried updating via com, usb etc: noting works, every time the same error.

At last I tries another computer with USB port: driver wasw loaded and USB port was visible as COM4. Via "Update Controller Firmware via USB" the program DFUloader version V1.4 of the firmware loaded into the SDC2130 card.
Hélas, after re-starting RoboRUN+ comes with the error "Control unit configuration menu file missing". When clicking away this message RoboRUN+ in Console mode continues sending ?TRN and ?FID commands. No connection possible. Also the buttons for "Update Controller Firmware via USB", "Update Control..." and "Update Poweer..." are not active.
"Update Controller Firmware via COM" gives the same error: "Device starting string not detected"

Also running DFULoader does not help. This program does not see the USB port / SDC2130. SO I am also not able to downgrade to V1.2

Help, previously I had a controller with old firmware, but working, Now I have a non working SDC2130 with updated firmware, but not working.

Hello,
Loaded the newest version of RoboRUN+ : WORKING!!
