I've finally bought Expert PDF 6 from 'avanquest' site. It works OK and encrypts any PDF document. It's not very user friendly, but most of us will manage it OK. It wont convert Microsoft Publisher documents. The cost on avanquest site was £39 I emailed them and told them that Amazon were selling it for £29. I got a reply allowing me to buy it for £24. So worth complaining!
Anyone thinking of buying - contact me first !!!!!!!!
