Regarding DW's stuff in the PC: DAZ has bought it and that makes it a DAZ Original, even if they didn't make it themself ;-). The David textures or the International Beauties are a DAZ Original as well but Morris made them. I am very sure when you loose the model you can still contact DAZ and they will find a solution. I don't think they would leave their customers alone in that case.
