Using Maya 5.0.1

I have an animated scene set up with Final Gather on. My previews come of perfect but I'm having serious issues trying to render out the entire scene.

On the 'Common' tab I have it set to
Frame/Animation Ext - name.#.ext
Image Format - Targe (tga)

All I get is a single IFF file (Not even sure what thes a re good for) and no TGA frames what so ever.

Am I missing something?
