I think if CL want to protect their products, a good start would be to provide printed manuals, and definitely not include PDF manuals on the CD or available as downloads. Pirates may spend time trying to break codes, but they are unlikely to type up a copy of the manual to go with it. How useful would the PPP be without a manual? Whilst there are PDF copies of the manuals around they will likely get copied along with the software, and give the pirates what is effectively a full package. Whilst printed manuals may cost a little to produce no doubt the software protection system is costing something anyway. Ian
