The two most common causes for this error are running out of memory or a corruption of some part of your project.
To check the memory, use the task manager to monitor memory usage during the export.
If your computer is not running out of memory, there may be something in your project causing the failure.
Consider these steps:
- Observe the % complete of the export when the failure occurs.
- Create a copy of your project using File->Save As and make a new name.
- Open the new file and remove one item at a time until the export succeeds. Maybe there is a filter applied around the point of the project where the export fails - start by removing something that is around the failure point.
- Continue to remove things one at a time until an export succeeds.
- Finally return to the original project file and remove just that one thing and recreate it.
Do not remove items from your original project. Only do this experiment on your copy of the project.
