Did you select to show Navigation? It’s not green by default. There’s a Show button in the upper left of the viewport, you can find navigation in there and turn it on.

If that’s on. Make sure the Nav Bounds are tall enough. Rebuild the level geometry as well, if it’s BSP it will probably need to get rebuilt.

Edit: Also, don’t use a preview version if your new to UE4, they have bugs and will make things harder for you. Use 4.11 instead
