Unknown HPSUSAN.

When you upgrade your computer, the new computer usually has a different
HPSUSAN (HP System Unique Serially Assigned Number; whew, what a mouthful!)
from the old one. Your Robelle software has a list of authorized HPSUSANs, so
when you move the Robelle software to the new computer, the software refuses
to run. Just call our office to get the new CPU authorized. The process takes
less than five minutes over the phone. There is no charge for replacing a CPU
with a larger one, although there is a right-to-copy surcharge if you are
adding another computer to the list.
