Icmai - de-novo or coaching re-validation

I tried to surf this forum a bit but I could not find an answer matching my query, so please excuse me if an answer does exist.

Query: I am a CMA Final student, I have not appeared in CMA exam in last 2 exams..I intended to give exam in December 2014 but on inspecting my CC certificate today,I found that my CC certificate was valid only upto June 2014 exam. Also my registration is valid only upto December 2014. I have exemption in one group expiring next attempt.

Is there any course of action that I can take to appear in December 2014 exam, I also saw that last date for revalidation paper sending is 15th September which is tomorrow.

However, if there is no solution to above query, I would like to know if I can appear in June 2015 through denovo and would I be required than to obtain new CC or I would have to revalidate my old CC.

Any help or guidance will be highly appreciated

Thanks in advance...
