Hi,
I want to offer you some help very much. But I am not using the tool you mentioned above. As for myself, I used to open and edit a pdf document with the help of another PDF SDK. It is just one of many but I do appreciate its simple way of processing. Even though I only tried its free trial package to process PDF documents and didn't check the cost and licensing conditions, it worked great for me.Here is the information about it:

Share with you. And I hope you success. Good luck.



Best regards,
