The Receiver is not your lawyer, and he cannot provide you with legal advice.  He was appointed by the Court and he is an agent of the Court.  He is executing the mandate of the Court.  As authorized by the Court, the Receiver will be investigating all potential claims or methods of recovery that he can bring for the benefit of investors.

You certainly have the right to hire or consult with your own lawyer.  You can also have that lawyer contact the Receiver if he or she has any questions about the case.
