施用microsoft agent时报错“未处理的COMException“

使用microsoft agent时报错“未处理的COMException“
private void Form1_Load(object sender, EventArgs e)
        {

            try
            {
                Genie.Characters.Load("merlin", (object)"C:/Windows/msagent/chars/merlin.acs");
                
            }
            catch (COMException)
            {

            }
            charater = Genie.Characters["merlin"];//此处报错：未处理的COMException The character ID is not valid.
Verify that ID has been defined and is spelled correctly.
            if (charater != null)
            {
                charater.Show(null);
                charater.LanguageID = 0x409;
            }
        }


------解决方案--------------------
没找到 merlin类型吧，看文件是否齐全
可把下面这条语句也放到try里面就不会报错了
 try
  {
  Genie.Characters.Load("merlin", (object)"C:/Windows/msagent/chars/merlin.acs");
    charater = Genie.Characters["merlin"];
  }
