Replying to Look FKS binding help

I fell backwards landing switch putting a lot of vertical pressure on the toe piece. I have some fks120s. I popped out of the binding and when I went to put it on there was a piece of plastic that had broken off between the wings of the binding and the base. It looked like this was cosmetic damage but the rest of the day I was coming out of the binding easily.

So has anyone had this happen before? Is there a solution? Is there anywhere that I can get just one toe piece?

Thanks a lot for your help.
