glow doesn't show up in other programs

[westy]

Hi guys I'm sure this is a really easy fix, but I'm not sure what's going on. I've rendered a simple line that glows and then fades out. (I've rendered it with an alpha channel) The glow shows up in the .mov file and everything is fine, however when I put it into after effects to be composited, it loses the outside glow completely. I've attached a picture of it with the glow, and then how it looks in after effects when it's supposed to be glowing- but of course nothing is really happening. The glow doesn't show up in other editing programs either. I can always add my own glow in after effects, but I wanted to know if anybody can tell me if I'm doing something wrong. Is it cause by the alpha channel? Thanks!

use your first image and use the luminosity rather than the alpha channel to mask the layer.
