Both of the issues raised in the thread appear to be completely unrelated.

We have a brand new Ultrastudio Mini Recorder and after installing Desktop Video, it started to update. The computer froze/crashed and restarted unfortunately and now the Mini Recorder shows no led light or power when plugged into any machine using any thunderbolt cable. Is there a way to reset it or has that broken it completely?
This appears that if the update was not completed, the advice Daniel provided is correct to contact us. You can find this information for your regions office on the support page.
As for Ciaran's issue; there isn't enough information provided for the other users here to assist you. Information such as the OSX you're running, the model of computer and what DTV version you're on would be beneficial to others to give you some guidance. You could also contact support for some additional troubleshooting if you require it.
