I have good news for you because your certificate for 35 contact hours does NOT expire. So you can submit your PMP application to PMI using the information on your certificate.
I have completed my PMP course from an institute and got my 35 PDUs in 2015. Not sure if the institute still have valid agreements to give PDUs or not. If the institute’s agreement is completed or never renewed, what happens to my PDUs? Are they still valid? I am planning to take PMP certification in Feb 2018
