Before posting, you might find the 'walk-through' of an installation useful: click here to view the installation guide.

A third thing to keep in mind - at least when installing in a *NIX environment - is that missing permissions might prevent AmpJuke from working.
A check for proper permissions is done when following the installation guide as well a during scan+import of music.
