save or load profile failure

Hi,
I’m creating an application in Java and at this moment i’m trying to detect mental commands. I’m using the MentalCommandWithCloudProfile.java example but i can’t save or load the user profile to the cloud. I have also tried the SavingAndLoadingProfileCloud.java example, also without success. I create more than one user in the cloud but always return the same failure result, however when i run the code for the first time to a new user the save works, but after that the save doesn’t work anymore.
Let me complement saying that i have tried to follow the steps to the training as shown in the code below (from MentalCommandWithCloudProfile.java) and i’m using Emotiv Epoc+ with the 3.3.3 sdk version.

"Please do follow steps:");
        System.out.println("A. Press 1 to Active training session.");
        System.out.println("B. Press 2 to Start training NEUTRAL. When completed, press 3.");
        System.out.println("C. Press 3 to Start training RIGHT. When completed, press 4");
        System.out.println("D. Press 4 to Start training LEFT.");
        System.out.println("E. Press 5 to Set ActivationLevel.");
        System.out.println("=============================================================");
        System.out.println("Otherwise, press key below for more:");
        System.out.println();
        System.out.println("Press 6 to Read ActivationLevel.");
        System.out.println("Press 7 to Get OveralSkillRating.");
        System.out.println("Press 8 to Save Profile Data to the cloud.");
        System.out.println("Press 9 to Load Profile Data from cloud.");

I lost hours searching in the forum but with no answer, so anyone can help me?
