This may be related to outstanding issue #1200 with Blender/Animation Nodes which is still being worked on.
Current workarounds for large animations are to try rendering from the command line. Make sure your work is regularly saved in case you encounter this bug.
The addons works best on meshes containing quad faces - that is, faces with 4 edges each. This doesn't mean your whole mesh has to be made of quads, as you can operate the addon on a sub-selection of faces. Other mesh topologies may work but are untested.
