how exactly do you stop syracuse?

SUGGESTED

We are working on an X3 version 9 install and found that we only had 8 licenses.  We have received our updated licenses, but cannot seem to get the license to install.  We have followed the instructions in the knowledge base (copied in the file, named it "license" with the proper extension) but we uncertain exactly how to stop syracuse.  We have started and stopped apache and have restarted the server numerous times, but the system is still not taking the new license and we cannot start an X3 instance as it keeps giving us errors that we do not have the correct license.  Can anybody help with a little more detail on exactly how to do this?
