Hi BCres,
the screenshot is not complete, but it seems that you have two Standalone licenses active on the same machine (M18).
Please close c4d on that machine, then open Standalone, go to File/Activation status, and press the Sign-out button, and close Standalone.
You need to have all the licenses listed in green as Available in your Octanelive page, before starting again Master and server.
If not enough, please write to [email protected], thanks.
ciao Beppe
