[Serusers] serctl restart

I have just downloaded ser-0.8.14_linux_i386.tar and unziped it... when i run the serctl start i get the error Starting SER : cat: /var/run/ser.pid: No such file or directory started pid() when i type "ser" on the command line i get : ERROR: bad config file (1 errors) and when i search for the ser.cfg i find that there is more than one copy if this file...which on of these does the sertctl and/or ser read? there is: /usr/local/etc/ser/ser.cfg /usr/local/etc/ser.cfg and since i ran the command 'tar -xvf ser-0.8.18_linux_i386.tar' from the root directory there is now a 'usr' directory in my root directory. therefore there is also a /root/local/etc/ser/ser.cfg and /root/local/etc/ser.cfg files which one of these files is used when i run ser and/or serctl start ser?
