This could be the result of a read or write error to file or disk, but it is more likely to be the result of an internal system error.
Alternatively, your application might have called many programs without canceling them afterward, so that memory becomes exhausted during animation.
Resolution:
Contact Technical Support who will help you to discover the cause of your error and how it can be rectified.
Ensure that as much memory as possible is available during animation by CANCELing any program you do not currently need to access.
