Hi there, I've been trying to update the firmware of my AF3 to the current v5.0.3 by downloading the newest editor and following the usual update procedure (select "Update Firmware" from the "FILE" menu in the editor and holding the rightmost footswitch on reboot as suggested by the dialog window). Updating the firmware has worked without problems in the past but now I always get the Message "An error occured". The progress bar that appears upon starting the the FW update process seems stuck at "zero" for about half a minute before i get the message. I've tried different USB cables, adding/removing a USB hub and changing the power supply (within the recommended range of specifications). The unit works flawlessly on its own and, prior to the editor update, editing via USB has been functional, too. My unit's current FW is v4.0.1, System is v2.4. My current main OS is macOS Sierra 10.12.6 but I've also tried to do the update on a Win8 machine which yielded the same results.
