Yes, thanks very much. I've changed the region to United Kingdom (which was one of the options in the box).
But how do I delete the PLL_Narrow_Boat_50ft_Pottery? I can't find it in the route (using Find Object). Isn't that what missing dependencies means in the CM? That it isn't installed? So, how do I delete it from the route if it's not really in the route? Do I just use the "Delete missing dependencies" option in the left hand menu?
This is all pretty darned confusing!!
