Okay, I signed up last year (2014) with May 14, 2016 as my wedding date. My wedding date has since changed to September 24, 2016. Every time I try to change my wedding date, it says "username invalid or already in use". I've had this username since I signed up, and I'm signed in with that username when it tells me it's invalid.. I've even tried to change my username multiple times in order to be able to change my wedding date.. It still always says "username invalid or already in use". Please help! Any ideas are greatly appreciated!
