Hi there, i was wo dering if anybody in here would be kind enough to help me out with a problem. I'm currently trying to create a simple AR app with an image target using vuforia. The thing is, i haven't been able to pin point the problem at the momento of built the app.

So far, everytime i click on build, every object dissappears and get deleted from the hierarchy tab. Additionally, the app that ends up getting build is just a freeze image of the sky tab (image added to show what i mean).

Anyway, I've been looking for answers everywhere and so far nothing has helped. So maybe somebody in here could guide me? Help me pin point the error? Show me a tutorial tha i haven't find yet to solve the problem?
