It's all good now, i just deleted the two profile files and it remade them when i ran the game again, i discovered this after re-downloading it...

I tried to change my DayZ name last night in the bottom right corner at the menu, and when i did it and pressed enter I got this error; http://prntscr.com/318pxy I have tried to change my name back, but I can't seem to find any file where i can, i looked in the cfg file but nothing about names, and i looked in the one that says my original name like "(name).DayZProfile" but it's just a bunch of gibberish. could anyone help me with this? thank you.
