"Bad mp3 directory" when installing mt-daapd on NS

Setup Info:
Version: 0.2.4-2 (stable release)
Server Hardware: NSLU2
Client: Roku Soundbridge M500

I have an NSLU2 with a Buffalo Ministation hard disk attached on Port 2. I have finally successfully unslung onto the hard disk after some problems. I then followed instructions on this site:
http://wiki.fireflymediaserver.org/NSLU2_Installation
Everything is fine until I get to the command:
# ps -ef | grep mt-daapd
At which point I do not get the required response, so (following instructions) I type:
/opt/etc/init.d/S60mt-daapd
But I recieve the following message:
Bad mp3 directory (/share/hdd/data/public): No such file or directory
Error reading config file (/opt/etc/mt-daapd/mt-daapd.conf)
When connecting to my NSLU2, I log in to ‘Private Data’ and see many folders that are refered to in the instructions. When I try to access the folders of the mp3 directory (/share/hdd/data/public) I can get to ‘share’ and to ‘hdd’ but when I try to access ‘data’ it opens an error message page saying:
The requested URL ‘%.80s’ resolves to a file that is not world-readable.
I’ve tried using vi to change the mp3 directory to /share/hdd/data/mp3 but this doesn’t change anything so I returned it to its original location.

Finally, when trying to type in:
/var/log/messages
It returns a ‘/var/log/messages: permission denied’ message.

If I can’t get my NSLU2 to serve up music to my Roku, I have completley wasted my money. I’m a beginner in this area of computers. Though I usually pick these things up quickly, I feel like I’m completely in over my head right now. Help! Please!
