I am a new user and have not been able to initiate Oculus sign in successfully. I typed in my email and pw and hit enter, but then I get a black screen on PC. My Rift headset has flashing red and blue bars with nothing else on it. I've reinstalled the OculusSetup.exe and did the repair but same outcome occurs. My windows updates are all up to date as well as checked that I have enough memory on my PC. Any suggestions to resolved this is much appreciated!
