preferences have not yet 
been created.
The pen display tablet was not detected at startup. Check that the 
USB interface cable is securely connected to a USB port on your 
computer or to a USB hub. Make sure that the pen display power 
LED is on. If this does not correct the problem, see Troubleshooting 
on page 29.
