When I got my FW about five months ago the case was very musty smelling as well. I lined the bottom with a couple of bounce sheets. I also had saved some of the little packages that come in shoes and other items that we buy. I'm told they are to keep things dry. I am not sure why I thought I needed to save them but I am glad that I did. But I put a couple of them in the case as well. The musty smell is pretty much gone.
