How to import from objects from Maya to Aero

I have tried every combination of formats and zipping to bring objects from Maya to Aero. Sometimes fbx work and sometimes dae works but most of the time they do not. I have also zipped the object with the textures included, and I make sure the textures are not too big. Its very frustrating because there is no consistency to this issue. Any help would be greatly appreciated.

Thanks

Don
