1) The "Swivel Pro" demo will not run off the CD. Copy the demo to your hard disk by dragging the "Swivel Pro" folder (located in the "More Information" folder on the CD) to your hard disk. You can then open the folder and launch the demo from there.
2) The "Swivel Pro" demo uses a lot of memory. If it isn't working for you, try quitting from other applications and/or turning on virtual memory. You can turn on virtual memory by selecting "Control Panels" under the Apple menu; double clicking the "Memory" control panel; clicking virtual memory "On"; and restarting your machine.
