Failed to create socket on UDP port 53 - Port 53 in use?

I am trying to setup PlexConnect on my Ubuntu 12.10 server. It creates a virtual DNS Server which is configured to run on Port 53. However it throws the error: DNSServer: Failed to create socket on UDP port 53

Which indicates that the Port is in use. However, I do not see it running: netstat -anlp | grep -w LISTEN tcp 0 0* LISTEN 26979/apache2 tcp 0 0* LISTEN 565/vsftpd tcp 0 0* LISTEN 682/inetd tcp 0 0* LISTEN 538/sshd tcp 0 0* LISTEN 564/smbd tcp 0 0* LISTEN 2505/mysqld tcp 0 0* LISTEN 564/smbd tcp6 0 0 :::443 :::* LISTEN 538/sshd tcp6 0 0 :::445 :::* LISTEN 564/smbd tcp6 0 0 :::139 :::* LISTEN 564/smbd

I am by no means a Linux expert, am I missing something? Is there another reason that I cannot assign the program to listen on 53?
