I failed PMP exam yesterday and I now know exactly which area I need to study more.

I am trying to reschedule the exam as early as I can but I cannot find any link for reexamination in PMI website. How can I schedule for reexamination online? 

In MyPMI section, it is still displayed as "You may now schedule your PMP examination" as it was before I take the exam. In the prometric website, my eligibility ID I used for 1st exam doesn't work anymore.
