TAPMI EDIT WINDOW

Hi guys, I made a major mistake while filling form for TAPMI, I need to edit it under any circumstance. I received a mail that the edit window will be open from 26th till 28th of Jan. But I tried last night after 12am, I tried multiple times today but I am unable to see any edit option. Am I missing something? Can someone please check and tell me if the edit button is enabled on their end?
