That model is very "heavy" I think the photo textures are making it very slow.
You should be able to move it, try deleting the Google earth layers that came with it. (both layers) to lighten the model. You will need to right click and unlock them, delete, then purge the model to get rid of the textures.
You should be able to move it, for some reason that model is very slow to work with.
I hope this helps.
