call to undefined function streamMp3() w/ 0.2a

Greetings, my ghettoblaster.protman.com used to work in IIS, but now on a
new server, I am getting an "undefined function" error on streammp3()

phpinfo()
ming
Ming SWF output library enabled
Version 0.2a

error log:
"call to undefined function streamMp3()"

Other Ming related functions are called first though with no prob...

<?
$basedir = "../mp3base";

  $m = new SWFMovie();
  $m->setRate(10.0);
  $m->streamMp3(fopen('$basedir/$mp3dir/$gbmp3', 'rb'));

  $m->setFrames($mp3time*10);

  header('Content-type: application/x-shockwave-flash');
  $m->output();
?>

I've tried capitalizing and decapitalizing the function call.

Any ideas?

Maybe the DLL I got was not compiled properly?

thanks!!
