@OP: If the dongle is no longer usable, please proceed with the Steinberg Zero Downtime. You will be also provided with a direct e-mail address when you apply for it in MySteinberg.
@Steve: Indeed, only Steinberg licenses. Every vendor have a different policy - especially concerning lost licenses.
@vic_france: Of course you won’t be asked to send the same dongle to different companies - we usually recommend to send a broken dongle also containing 3rd Party licenses to the 3rd Party. We do communicate with them and have a support service for vendors as well.
