Because this is the CS4 SWC it requires that you compile using Flash Player 10 as this version supports these properties for 3D rotations

hi! i had the same problem. this is easy to fix. instead of: _current.scaleX just use: _current['scaleX']

so this does not trace you an 1119-error regards, daniel
