Ae CC Import rendering mov = Crash

hello,

A new problem in Ae CC.

For recreate the crash :

I Rerender (replace ancien)  .mov in C4D

When i come back to Ae (the render isn't finish) Ae importer CRASH ! and don't save !

In CS6 i never saw this problem.

I can't increment my render every time.

I am ok to clic right and Reload footage. Someone know how to modified the correct file to stop automatic update of footage ?

Thanks a lot !
