Plz Help

Hey, i just got back to the server and tryed to login, when i got in all my characers didnt have names, so i made new ones and login. But i forgot to rename the "wtf" folders before i loged in, so all my ui s got fked.
anyone know if i get my ui's back and how?

can't you just rename the old files to corresponding new characters' names?

i did, but i loged in and loaded the addons without the save from the wtf fills, so it saved over my old addon setting
