TOPIC: PM Prepcast Exam Prep

I purchased my pm prepcast, simulator and formulas prior to Sept. 2017 and if I am reading the information correctly on the website that because I have to take the exam after March that I will be required to pay the full price of the course and additional material all over again. Would anyone be able to confirm this? Doesn't seem very customer service oriented that if we already paid over $300 for the course that we have to pay another $300 just because the PMI was updated to new material.
