trying to start up a new station..getting this error when start stream

stream could not be started: Application liquidsoap exited immediately after startup.

any ideas? thanx

Centos or Debian/Ubuntu?
There is a little bug in the Centova Installer, so that a extra Call is needed.
try this inside the Terminal/putty
/usr/local/centovacast/sbin/enable_package liquidsoap /usr/local/centovacast/liquidsoap/bin/liquidsoap
and after that check if the autodj will have Encoders.
Because after a fresh install there are no Encoders in autodj.

this is what shows....

looks like the Port (in your case (8538)  is in use.
just ceck your ports with
lsof -i

or
netstat -tulnp
