Feral Heart

Okay so i changed my character for a little bit, and i go to change it back and whatever i do it says "name cannot start or end with spaces!" I DONT KNOW WHAT TO DO!!! i cant delete the character because it has a huge group im running on it!!! HELP WOULD BE APPERICIATED!!! And i cant reinstall either if it means LOSING the character!

EDIT: Okay i guess is this confusing to some, Basically i try everything from canceling to changing the name! No matter what it will NOT let me do anything!! (and i just wanna change the size too!!)
