It worked like a charm, but although I figured it would be a paid service, but it would have been nice to know it was and how much before I got started.

Its a real good software, I think that people really can used it, maybe there should be a program that pay by used not a regular monthly charges. I am a every six month user.

Only thing it is lacking is the OCR - If it would have had this ability to edit scanned pdf document like PDF element - then it would have been the best!
