There have been several posts with this problem, but no answers. When I download the tutorial file GameTutorialResources it is a .tar file and not a Unity Asset package so cannot be imported into Unity. It seems to have been a problem 4 or 5 years ago but not resolved. I want to evaluate the trial package with a view to buying the full version but won't be spending $100 on something I can't use. Has anyone got an answer please?
