Ekos is not able to create a preview. I'm following an online video on how to use Ekos with a DSLR , and is connected to my Nikon D5100. However, when I try to capture, I get an unspecified error, as listed in the screen grab below.

I also get an warning about saving to an SD card, but I don't have Ekos set to save to an SD card.

I also try to set the resolution to the camera's 4928x3264 14-bit resolution, but when I restart Ekos the data is not there, as is shown in the screen grab.

Any ideas why capture is failing? The video I'm watching is rather old and has a different Ekos, but everything panned out until I tried to capture.

Thanks for any info on this.
