Can't find my shapes inside rotoshapes? All my "Shake" shape data gone

I opened a file which I did over two weeks of roto work on and all my shape data inside the rotoshape nodes are gone? I can create new shapes in exsiting roto nodes and it holds the data.

I recently when from Shake 4 to 4.1 -- Other files are working ok. Can someone help me recover my shape data?
