Jipmer — regarding payment in jipmer mbbs application form

Sir
My name is ankit gourav (Reg id - 147850). I have submitted the application form of jipmer and go to payment and fill the details when i click on payment option it shows error.
Now when i log in again it shows "go to application form and make payment" when i click on go to application form it shows edit function is available b/w 5th of march to 2nd of april.
But i have already submitted the application form then why this shows and doesn't go to payment box directly.
Sir please look into this problem and solve as early as possible.
