Help with a Lamp that doesn't light correctly

Yesterday, I posted about this but I was so sleep deprived that evidently I didn't click "create thread." I can't find yesterday's post. 

Anyway, I made a lamp that isn't lighting correctly, and I'm thinking it has to do with how I vertex painted it, but it might be that I cloned the wrong lamp--I cloned the same lamp that OM did in her tutorial. I'm also a little confused about what "At" (in-game coordinates?) is in the warehouse section of Studio (per OM's tutorial: sims4studio.com/thread/4803/make-new-lamp-lights-correctly). I'm wondering too, if I need to change the light type in the warehouse tab--say, from "AmbientLight" to "DirectionalLight" or something. I'm not clear on what those different light types do. 

What I want is for the cone/nose portion of the rocket to be lit--everything above the blue "stripe"--and I'd like the light to be directed upward, if possible.  

Here's what it looks like in Studio:




And here's what it looks like in game:




 Here's my .blend and .package: Link for to be clicked

And I haven't done the specular, bump map, or the LOD 1 yet, but I don't think those are what's causing my issue.
