After Effects automatically not responding and then exit.

Hi to all,
When I try to close or exit the application, the software crashes.
The project I am creating is not that complex neither a large file.
It’s just a simple project. A simple animation with moving graphics.
How can I avoid this?

After Effects error: Crash in Progress. Last logged message was: <1296><D_MCp_SetupExporterModule><5> Ignoring: 1230389550 1464094018
Thanks for your help.
