Endorsement Letter expired during the proccess

[flaviasegond]

I've sent my application for PR under the Atlantic Immigration Pilot Program by mail (Im in Brazil), and after 6 months without updates the Immigration returned my applycation because there was a mistake on my Generic Form. So by the time that they returned the application, my endorsement has already expired due to the their delay in processing it. Should I correct the mistake and send it back? I dont know what to do. Any advice?

You need a new endorsement letter as extensions are not allowed.
