Hi Jonathan,
To reduce your file size, you can clear the solution and the mesh. In 4.3b, you can do it through the edit menu (at the right of the file menu) by selecting : clear all meshes and clear all solutions.
I did not open your model, but my first guess would be the air electrical conductivity. By default, it is set to 0. In order to get a convergence, you should try a higher value (10 for example) and then make it decrease until it converge.
Hope this helps.
