[away3d] Another [1046: Type was not found or was not a compile-time constant: DListNode.]

[zerodevice]

I know this has been asked and probably solved.

I am trying to test WOW for my 1st time, but it gave me this error
when all i did so far on the wow part was.

//wow
import fr.seraf.wow.core.WOWEngine;
import fr.seraf.wow.core.data.WVector;
import fr.seraf.wow.math.WVectorMath;
import fr.seraf.wow.primitive.WOWPlane;

var wow:WOWEngine;
wow = new WOWEngine(.3);
wow.collisionResponseMode = wow.SELECTIVE;
wow.addMasslessForce(new WVector(0,6,0));

i was told that the path is probably set wrongly.
but i have no leads to how it should set.

Here's my path:
C:\Website\castle_swf
C:\Website\castle_swf\away3d.
C:\Website\castle_swf\com
C:\Website\castle_swf\fr
C:\Website\castle_swf\side_banner.fla

And here are the errors displayed.
1046: Type was not found or was not a compile-time constant:
DListNode. -- WOWEngine.as, Line 191
1046: Type was not found or was not a compile-time constant:
DListNode. -- WOWEngine.as, Line 202
1046: Type was not found or was not a compile-time constant:
DListNode. -- WOWEngine.as, Line 216
1046: Type was not found or was not a compile-time constant:
DListNode. -- WOWEngine.as, Line 241

Please show me some light.
Thanks in advance.
