Hi underdog91!
You do not need to submit any additional forms in order to update your proctor's address information. This can be done over the phone by calling us here in the Proctored Exam department at 1-888-427-1000. We can update the information for you and then order a new exam for shipment, as it looks like an exam was shipped in the beginning of June to your proctor at their old address. I would ask that you please double check with your proctor that the exam was not received or forwarded to them prior to us ordering a new exam.
Please let me know if you have any additional questions, and good luck with your studies!
