Currently using Unity 5.6, when I install Playmaker 1.8.4 for Unity 5.4 and above using the download link from my original email, I receive a notification that the API needs to be updated. However, it immediately then says the API was unable to update. If I tell it not to update the API, I am then presented with this error.
