I would try to deactivate v3.00 and then try with v3.01:I appreciate you helping me out man. I redid the terminal thing (using select all to make sure I had exactly the right code), but it still showed me the same error message. I then clicked 'sign in as another user', it then showed me the login screen. After that I quited Octanerender redid the terminal command and it went straight to the login screen, the same as in your video.
Then I downloaded Octane v3.01 using the link you provided. Opened that up, logged in using my credentials and got the error message 'Could not find the required license - Unable to find the required license'.
The Octane Licenses screen remains unchanged.
