I can't make PiPlay 22.214.171.124 work normaly with Steam VR. I'm reciving error code 400 or error code 306. I've wrote to Steam support, but they can't help. They said that I should speak with Pimax support.
I've updatet and reinstalled all Nvidia drivers (I have GTX1080 8gb), reinstalled all Steam related software, reinstalled PiPplay dosen of times, nothing helps.
The old version - PiPlay 1.1.92 runs SteamVR just fine, I've rolled back to using it for now. What ealse should I try?
