Welcome to the family!
To access the Quick Start Guide, type "quit" into the command line, followed by Enter. This will take you to the desktop. If you then navigate to the C:\CMI30A\Manuals directory, (click the Start button at the lower left of the screen, then double-click OS (C:), then double-click CMI30A, then double-click Manuals), you will see the "CMI-30A Quick Start Guide.pdf" file which you can open using Adobe Acrobat or copy to an external drive.
To shut the system down, type "shutdown" into the command line, followed by Enter. If you're presented with a "You're about to be logged off" dialogue box, click the "Close" button and the system will then shut down.
To backup libraries, quit the CMI application then you can then copy libraries to an external hard drive or to DVD in the normal way.
If you have any problems or questions just email me.
