Button highlights and on hover functions(colors or .pngs) do no work once packaged

Button highlights and on hover functions(colors or .pngs) do no work once packaged…They consistently work fine in editor mode before packaging. I have tried everything(layering, widget reflector etc)…It stinks to build a great menu and then none of the parts that make it worthy of a good menu even work…I am up for any suggestions at all…
