Papervision 3D error

programming flash
1

I have two classes,

  1. remoting.as (something using AMFPHP)
  2. colladaObject.as (papervision)
    they both work fine apart in seperate projects, but when I put them together and reference the class paths they need, I get this error:
1020: Method marked override must override another method.

Seems when I reference the AS3 project publish settings to the GreatWhite src and my default ‘classes’ there is a conflict?! As far as I know I have narrowed it down to this. It only seems to happen when I reference the 2 together. On there own they only need one or the other.
What shall I do?! PLEAASE HELP!
