Unknown Error: 773. Training cognitiv in Unity

Hello, I bought the Unity Wrapper for a project and am getting an Unknown Error: 773 when trying to train commands
I am initializing training like this:

EmoMentalCommand.EnableMentalCommandAction(EmoMentalCommand.MentalCommandActionList[5], true);
EmoMentalCommand.EnableMentalCommandActionsList();
EmoMentalCommand.StartTrainingMentalCommand(EmoMentalCommand.MentalCommandActionList[5]);

I was under the impression that the error 773 code means that the action has not been activated but that is handled by EnableMentalCommandActionsList().

Please advise
