yeah but you cant use the split poly tool on a subdiv. At the moment you have a subdiv mesh not a poly. you really shouldnt have deleted the cage cause that's what you would have used the split poly tool on. Do you have an older saved file? either that or convert the subdivs to polys (but the mesh will be dene as hell)
sorry
