Models Exported from Blender Always Invisible

[ZutaraRaven]

After getting frustrated being unable to import the models I downloaded into the Model Editor, I decided to go and follow the steps here exactly:

As it turns out, it's still a no-go.
I'm using the latest version of blender, I actually just got a fresh download today. I can always see the shapes of my models in the Model Viewer, but whenever I go into the Model Editor to get the model game-ready, it's invisible. When I click the area where objects appear by default, I can see the kind of 'mesh' that lets me know it's there, but otherwise it's just being a ghost.
Also, when this happens, if I try to load a second object that I had tried exporting from blender, the Model Viewer crashes.

I have used jpegs for the textures on the blender models and have followed the steps in the wiki linked above to get it export ready, then moved the collada some place into Amnesia's redist folder for easy access.

And dammit, I've been searching the far reaches of the internet for a solution. There's gotta be something I'm missing here.
