Usually that means there is a bad path in the minion.xml. Can you attach that file here?
On osx the easiest way to get to your minion.xml is open a terminal window (under applications, then utilities) and type in this:
Code:
cp ~/.minion/minion.xml ~/desktop
and the file will appear on your desktop so you can attach it to this post.
The log file can also be helpful and you can do this to get it...
Code:
cp ~/.minion/minion0.log ~/desktop
