Yeah Let us know as we probably have more ideas to try out.
Thanks for the info aswell. The older 192 and 96 interfaces works great with HDX and HDN/TBolt cards so just wanted to make sure you had an interface connected for PT to see the HDX card.
If none of the ideas work I would try moving the card to a different slot. This has helped before so worth a try.
