Toonboom studio 8.1 keeps crashing

My work is up to nearly 1000 frames when i try contour editing a drawing it crashes. Im running it on a minimac 2.5 ghz 4gb RAM and 512 graphics. Can anyone help.

As far as I know, Toon Boom doesn’t work very well with Integrated Intel Graphics…?
Split your Projects / Scenes into smaller parts…
