Ipcc revalidation query

Dear Sir,

I have registered for CA -Ipcc and successfuly cleared first group of Ipcc in August 2012 now my old registration expired in this January and I have filled up my revalidation form on 3rd Feb,2014. Now my question is can I submit my exam form for May-2014 for Group 2 and what procidures I should follow for this. If my revalidation letter will not come upto expiry date of exam form then how can I apply for May-2014 and what should I do now?

Please reply as early as possible.
