Cannot see reference image when drawing

Hi guys, my brother and I are new to Toon Boom (animating in general actually) and we have hit a hurdle right at the starting line! We want to import a raster image to animate over in vector but every which way we try we cannot draw on a separate layer and still see the raster pic.

I’m wondering if it’s to do with the fact that we’re using the trial for Advanced at the moment?

Any suggestions?
