I am running a flight simulator made with Unity 5.4.3f1 which was working perfectly until my Oculus automatically updated to 1.20. Since then my computer (on Windows 7 with a graphic card NVIDIA GeForce GTX 980 version 388.00) freezes randomly when the Oculus is plugged in. Sometimes it happens in the middle of a run and sometimes I cannot even open Unity. The only way to de-freeze Unity (the other programs are working) is to un-plug the USB cable and then Unity re-works perfectly fine. Can anyone help me with this? Or is it possible to re-install the 1.19 version which was working perfectly?
