editor issue after install

Great little plugin, saved me alot of time when I had to upload a ton of mp3’s.
Once issue now though is, I installed it, activated and used the plugin but not my post editor is not working, as in can’t type in the editor field at all and even when I try to create a new page, I can type in the page title field but the editor won’t let me type anything in there at all.

I have de-activated the plugin and uninstalled it, but still no joy.
I’m using WordPress3.5.

Any suggestions?

Thanks
