Behaviors not workin in TGB 1.7.2?

'lo there folks.

this is the problem:
i had a Geometry Wars clone project made with TGB 1.5.1 which i stopped workin on about 4-5 months ago, it happens that since im now workin with TGB 1.7.2 i wanted to load it up with it, and then TGB asked me to update the project, so i could use it in the level editor.

i did update the project when requested, and hoped everythin worked fine, but whenever i hit the F5 key, the starts workin and stuff, but the behaviors just dont run...

this is the code i use to assign and get behaviours runnin:

%shipControls=ShooterControlsBehavior.createInstance();

  %shipControls.upKey="keyboard w";
  %shipControls.downKey="keyboard s";
  %shipControls.leftKey="keyboard a";
  %shipControls.rightKey="keyboard d";
  
  %this.addBehavior(%shipControls);
  %shipControls=%this.getBehavior("ShooterControlsBehavior");
  %shipControls.onBehaviorAdd();
  
  %this.shipControls=%shipControls;
  
  
  %faceMouse=FaceMouseBehavior.createInstance();
  %faceMouse.rotationOffset=-90.0;
  %faceMouse.turnSpeed=0.0;
  
  %this.addBehavior(%faceMouse);
  %faceMouse=%this.getBehavior("FaceMouseBehavior");
  %faceMouse.onAddToScene();
  
  %this.faceMouse=%faceMouse;

in the past (TGB ver 1.5.1) it worked like a charm... now its givin me the followin error:

game/gameScripts/player.cs (48): Unable to find object: 'ShooterControlsBehavior' attempting to call function 'createInstance'
game/gameScripts/player.cs (60): Unable to find object: '0' attempting to call function 'onBehaviorAdd'
game/gameScripts/player.cs (69): Unable to find object: 'FaceMouseBehavior' attempting to call function 'createInstance'
game/gameScripts/player.cs (75): Unable to find object: '0' attempting to call function 'onAddToScene'

whats goin on?... hast the behaviour management and stuff changed in TGB 1.7.2?

help anyone?


Thx in advance.
