Hi,
you need to clean your assets.
- Move all templates and global asset out of the Asset/PlayMaker/ folder
- Delete Asset/PlayMaker/ folder and the Asset/Plugins/PlayMaker/ folder
- Import PlayMaker from the asset store
- import the package from Asset/PlayMaker/Editor/Install
Then you should be good, else, try to import the last step it one more time ( it helps as some editor routine might still not have fully worked because of Errors).
Bye,
Jean
