Mine is also doing this. I'm not using a splitter, and both ends of the cable are fully inserted. It was working fine until I updated the firmware. If I unplug the cable and plug it back in, it just gives me a circular arrow in the center that never goes away (I left it for well over an hour earlier today). If I close the software and open it back up, I'm brought back to a page like shown above with no profiles. No option to calibrate. Why isn't this working now? I'm going to try removing the software and reinstalling it. Just glad I took a pic of all my keybinds before I updated.
