TableTools not working (but was)

charitygrace

I'm at a bit of a loss as to what's going on. The TableTools swf file appears to installed correctly except the buttons don't show (safari) or the buttons don't work (chrome).

The buttons stopped working in an old version, but now I've upgraded to the latest software and they still aren't working. Here's my most up-to-date dev version:

If I try to open the swf file url in my browser, I indeed download the swf file, so it appears I have called it correctly.

Here's the js for the DataTable and TableTools call:

$(document).ready(function() {
    $('#datatable').DataTable( {
      "dom": 'T<"clear">lfrtip',
      "bPaginate": false,
      "tableTools": {
        "sSwfPath": "http://farmtrails.org/js/copy_csv_xls_pdf.swf"
      }
    });
});

Can someone help clarify what I'm doing wrong? Thanks.
