Morae: Error: An unnamed file contains an invalid path

Problem

An unnamed file contains an invalid path

Solution

This can occur if there are problems with the Morae temporary file folder or a corrupt temp file exists that cannot be opened. 

There are several things to try

1. In Manager select File > Preferences and delete any temp file that may exist.
2. In Manager select File > Preferences, and change the Default Project Directory and also your Temporary directory. Try changing it to: C:\Morae.
3. Uninstall / reinstall Morae.
