You should definitely file a support ticket, so that we can keep tabs on the issue.
As a work-around, you can try the following:
- Unplug the Form Wash or Cure from power, and wait about 10 seconds for it to power down.
- While holding the front button down, plug it back in.
- At this point, it should show up with a button labelled “Resume update” in the FormWashCureUpdater application. Press this button, and the firmware update should proceed.
