[Papervision3D] Error 1009, help

[Gaurav Khanna]

if i do scene it throws this error, same as if i took out this but a little
different
ReferenceError: Error #1069: Property rootNode not found on
org.papervision3d.scenes.Scene3D and there is no default value.
    at main/::loop3D()

also tried stage and it gave sort of the same thing except it was for
flash.display.stage, its ok though, those two errors arent cause by whats in
the parentheses and quotes at the end cause i'm not sure if i have those
right and i think thats the problem, i already tried Focus and raceCar1
which are the probable things, and just tried out Car1 and that didn't work
either ughh lemme see what else i can do
