The problem is solved. I really thank you all for your time and your help!
I modified a code from another voicedcommand, which was used via Powerpak. What I did, was add these to Powerpak.java
Luck luck_handler = new Luck();
VoicedCommandHandler.getInstance().registerVoicedCommandHandler(luck_handler);
CustomBypassHandler.getInstance().registerCustomBypassHandler(luck_handler);
System.out.println("Luck is Enabled.");
