[Unity SRworks demo problem]

Hi! Hope you can see my inquiry.

I use unity 2018.4.30f, srwork 0.9.7.1, steamVR1.15.19.

I follow the step as @Tony PH Lin mentioned:

1. asset srwork to unity 2. restart unity 3. asset steamvr 4. asset SRexample 5. run demo

But it still can not work...

here is the problem:

NullReferenceException: Object reference not set to an instance of an object
Vive.Plugin.SR.Experience.ViveSR_Experience_Initialization.CheckCurrentHMDDevice (System.Action done) (at Assets/ViveSR_Experience/Scripts/ViveSR_Experience_Initialization.cs:90)
Vive.Plugin.SR.Experience.ViveSR_Experience_Initialization.<CheckBasicStatus>b__3_1 () (at Assets/ViveSR_Experience/Scripts/ViveSR_Experience_Initialization.cs:24)
ViveSR_Experience_ActionSequence+<StartActionSequence>d__8.MoveNext () (at Assets/ViveSR_Experience/Scripts/ChairSegmentation/ViveSR_Experience_ActionSequence.cs:47)
UnityEngine.SetupCoroutine.InvokeMoveNext (System.Collections.IEnumerator enumerator, System.IntPtr returnValueAddress) (at C:/buildslave/unity/build/Runtime/Export/Coroutines.cs:17)
 

I want to know what happened? And how to solve this.

Waiting for reply.
