I don't think that necessarily means new applications will not be approved for the 2nd quarter. It may just be a meeting with Prometric do determine what the issue was, and ensure that it won't happen again.
I would also add/suggest to invest in Reza Mahallati's workbook. The problems in that book are more difficult than the actual exam, but prepare you very well imo. I used CPESR and Reza's book and passed on my 2nd attempt.
