Download DirectX Model viewer. Its free and shows you what your models will look like.
I use Blender and you have to make your model HUGE in comparison to the grid for it to be scaled properly in FPSC. Make sure that your model is scaled properly, otherwise, that 'little dot' might actually be your model, just really tiny!
What Tazman said is also correct, make sure to check that all the necessary files are in the folder. (FPE, model.x, all textures (D2, N, S))
