My font material is showing up blank white?

So I am trying to use a different font than the default UE4 one. I dragged in Arial and created a new fort with it just to make sure I could do it. But when I try to use Arial the font material goes blank. Any suggestions or insight would be super helpful- Thanks!

I have the same Problem. Did you found a solution?

fixed it. Open your Distance Field Font Texture, click on your Font in viewer, search for compression Settings, change to DistanceFieldFont (R8).
