The Conjecture is still open.

Lemma 5 of math.GM/0204209 is false. For example, any primitive group on a prime number of points is a counterexampleto Lemma 5.

Lemma 6 of math/0506617 is also false. Any transitive permutation group without a derangement of prime order satisfies the hypotheses and does not contain a semiregular element. (Any semiregular element has a power that is stil semiregular and of prime order.) Such groups exist, such as $M_{11}$ acting on the twelve points.
