It should work, what script are you using. This script should work:
_root.createTextField("msg_txt", 3, 30, 222, 500, 40);
msg_txt.multiline = true;
msg_txt.wordWrap = true;
msg_txt.embedFonts = true;
msg_txt.background = true;
msg_txt.type = 'input';

var my_fmt:TextFormat = new TextFormat();
my_fmt.color = 0x0000ff;
my_fmt.underline = false;
my_fmt.size = 28;
my_fmt.align = "center"
my_fmt.font = "VAGRounded BT"
msg_txt.text = "YOU ARE HOT B";
msg_txt.setTextFormat(my_fmt);

No wait, this should work:
_root.createTextField("msg_txt", 3, 30, 222, 500, 40);
msg_txt.multiline = true;
msg_txt.wordWrap = true;
msg_txt.embedFonts = true;
msg_txt.background = true;
msg_txt.type = 'input';

var my_fmt:TextFormat = new TextFormat();
my_fmt.color = 0x0000ff;
my_fmt.underline = false;
my_fmt.size = 28;
my_fmt.align = "center"
my_fmt.font = "myFont";
msg_txt.text = "YOU ARE HOT B";
msg_txt.setTextFormat(my_fmt);
