Image_FUpload CCK

I've installed the image_fupload CCK module on a site we use internally. All the dependencies seem to be present but Image FUpload CCK says it's "not usable yet (missing).

I did install the latest 2.2 beta 5 of swfupload.swf, swfupload.js, swfupload.queue.js in sites/all/modules/image_fupload/swfupload and I've checked other modules...

I'm a bit stumped as to why it's not working...

Thanks...
