Steps to reproduce:
1. Create new Unity project
2. Go to PM > My Assets
3. Install and import one of the available Assets (for example: “Starter Assets - ThirdPerson | Updates in new CharacterController package”)
4. Once the assets are installed press “Validate” button
5. Observe the Console window
Actual results: "NullReferenceException" error is thrown after pressing "Validate" button
