Unvalid import settings when converting image to an image target in Unity 5.5.1f1 Personal (64bit) with Vuforia 6.2 SDK

Hello,

I have “Unity 5.5.1f1 Personal (64bit)” and “Vuforia 6.2 SDK” (vuforia-unity-6-2-10.unitypackage).

I converted my image into an image target using Vuforia Target Manager, and I need to associate it with my ImageTarget prefab in Unity. I imported the database package which I got from Vuforia (a .unitypackage file) in Unity.

However, I got this error: "Package does not contain valid import settings for: Assets/Editor/QCAR/ImageTargetTextures/Example1-200px/Example1-200px_scaled.jpg"

What do I need to do?
