ckeditor+ckfinder integration no go after upgrade and config

Hey guys, I've been scratching my head for a few hours on this so I'm really hoping you guys can point me in the right direction.

I have upgraded to the latest versions of CKeditor and CKfinder. I renamed the two earlier folders ckeditor.old and ckfinder.old so I'd have a backup and then I replicated the settings from the OLD ckfinder/config.php into the NEW config file.

The new (and the old) were installed in a subfolder of the root:
tbs/ckfinder
tbs/ckeditor

The paths are the same as before and the ckfinder/config.php is set the same and yet the "Browse Server" button does not appear any longer. The crazy thing is that if I rename the new ckfinder folder to ckfinger.new and I rename the old ckfinder.old to ckfinder the button appears right away again, so I know it's something in the new ckfinder, but I can't find what it is!

In case it matters, in my page I have this:

<script type="text/javascript">         
   // This is a check for the CKEditor class. If not defined, the paths must be checked.
   if ( typeof CKEDITOR == 'undefined' )
   {
      document.write(
         '<strong><span style="color: #ff0000">Error</span>: CKEditor not found</strong>.' +
         'This sample assumes that CKEditor (not included with CKFinder) is installed in' +
         'the "/ckeditor/" path. If you have it installed in a different place, just edit' +
         'this file, changing the wrong paths in the &lt;head&gt; (line 5) and the "BasePath"' +
         'value (line 32).' ) ;
   }
   else
   {
      var editor = CKEDITOR.replace( 'data' );
      CKFinder.SetupCKEditor( null, 'tbs/ckfinder/' );
   }
</script>

I also tried with:

CKFinder.SetupCKEditor( editor, 'tbs/ckfinder/' );

and in my head tag I have:

<script type="text/javascript" src="tbs/ckeditor/ckeditor.js"></script> 
<script type="text/javascript" src="tbs/ckfinder/ckfinder.js"></script> 

I am totally stuck so ANY help would be GREATLY appreciated. Thanks so much in advance!
