[Serusers] Starting SER : PID file exists (/var/run/ser.pid) already running?

Hi, I am wondering if anyone has ever come across this error before?: Starting SER : PID file exists! (/var/run/ser.pid) already running? I am using ser 0.9.0 and it worked like a charm the first few times that I stopped and started SER. There are no errors in /var/log/messages. I also started SER as /opt/ser/sbin/ser -c and it showed that the config was ok and exited. However when I check pstree, I dont see SER listening. Could it perhaps be something got to do with the database?. Example: Should the version table in the SER database contain "version" or "table_version"? I have tried dropping and restarting the database i.e. /opt/ser/sbin/ser_mysql.sh drop, then ./opt/ser/sbin/ser_mysql.sh create. Any ideas would be appreciated.
