I never learned Y_Ini, so you can change:

pawn Код:

CMD:changenick(playerid,params[])

To Y_INI command starter:

pawn Код:

Y:INI:changenick(playerid,params[]) // I don't know :D

I made him in Dialogs, and it's very simple, you can optimize him.

P.S: Works fine. If don't work, some of your filescripts it's blocking him .
