How to re-download Video Decoder for Avid DNxHD

Did as you said - I started ELC, let it update, entered the activation code for the decoder, which of course it didn’t let me do as it’s THERE already, started Nuendo and still no joy. Tells me I’m still missing the DNXHD decoder.
All that aside - I’m pretty sure I had to install it separately last time, so I don’t think it is included in the Nuendo installer.
Don’t know if I’m missing anything, but if A: the license is on my dongle and B: my ELC is updated, I don’t know what else could be wrong except I still need to install something.
This is really angering me. It’s been more than a day since I contacted Asknet, I’ve got work to do and it’s going crap doing it with the H264 versions I had to convert from my DNX files… :frowning:
