D. holding that amendment is futile if the proposed amended complaint does not state a claim upon which relief can be granted
E. holding that a plaintiff is not required to file an amended complaint when his complaint is involuntarily dismissed without prejudice and that for the purposes of appeal such a dismissal is a rule 41b adjudication on the merits
