It worked and now it doesn't because the "developer.keystore" used by KUAL expired yesterday morning.

Until KUAL gets a new release the only way to keep using the old/existing one would be to intentionally set the date/time on your Kindle to wrong date that's XY days in the past, so you fool the device in thinking that certificate is still valid.
