EDIT : the problem was the CACHE jaja

SOLVE HERE

www\system\libs\validator.php

    if(!preg_match("/^[A-Z0-9]+$/i", $name))
        {
            self::$lastError = 'Invalid account name format. Use only A-Z and numbers 0-9.';
            return false;
        }

Remplece to

  if(!preg_match("/^[0-9]+$/i", $name))
        {
            self::$lastError = 'ONLY NUMBERS';
            return false;
        }

and clean cache xd
