From time to time there will be an update for Sue Center.
You will notified by email that the update is ready and why you would want it.
To actually do the update, enter 'UPDATE' in the message area and then choose 'Go'.
The 'updater' is downloaded, Sue Center is terminated, and the updater is run. It will download the files it needs and adjust any needed configuration files. Sue Center will then be restarted for you.
Rest assured that these updates will never lose any of your personal files nor your customized settings. They will, hopefully, simply make Sue Center better!
