Can anyone help me with couchpotato

I have set up couchpotato and it works great (with sabnzbd) with torrents (transmission) things go wrong.

The file gets downloaded but stays in "incomplete-dir" where when you manually add a file it goes to "complete-dir" after finishing.

Also the renamer doesn't rename nor move the file to the "movies" directory.

I'm running ubuntu server 12.04 does anyone know how to resolve this issue?
