Here is a work in progress that is intended to be of assistance to people with basic problems running Octane.
It doesnt cover every issue, only points you to likely causes and remedies.
This might lessen the need for new people to ask much the same questions over again in the forums.
I wont be answering this thread to provide software support and this isnt an official Refractive post but feel free to post any comments about the help content itself so it can be refined.
Hope it helps other users find their way.
BTW to help others to help you please add your hardware and O/S details into your forum signature
