UnitySteer can't find some scripts

I’ve downloaded UnitySteer examples from github, imported UnitySteer package from Asset Store. When I open SteerToFollow scene and click on any Follower object, it can’t find some scripts. I need to make following with UnitySteer, so I must see these following examples. Hope someone help :).

Not sure if this helps.
1st Item = Radar Ping Script
2nd Item = Randomize Start Position Script
3rd Item = Autonomous Vehicle Script
4th Item = Steer to Follow Script
5th Item = Steer for Separation Script

Keep in mind, I tweaked mine a bit, but this works nicely. I like to have the Vehicle above the Steering.
