Could you please elaborate on the editing operation(s) that you are trying to perform on the FormsCentral PDF?
Note that the PDFs created by FormsCentral are "Reader-extended" to enable additional features when the form is opened in the free Adobe Reader. This restricts certain functions, such as editing document content or inserting and deleting pages within Acrobat.
To generate a version of the PDF that does not have these restrictions, open it in Adobe Acrobat and select the File | Save a Copy... menu item.
I have created a PDF file by Forms Central. I did what you have instructed and it worked!! thank you very much!!! However, now I am having another problem. In Adobe Acrobat, I selected the File, Save a Copy, then I was able to edit the file. I have added a signature field at the end of the page. Then, I save as it as Reader Extended Feature PDF file. So, I can send this file to other people in my company to sign it with Adobe Reader.
The problem is whenever they open the file with Adobe Reader, it shows "This document enabled extended features in Adobe Reader. The document has been changed since it was created and use of extended features is no longer available. Please contact the author for the original version of this document." Everytime, I send this file through email, the security setting changes, which the reader extended feature will disable by itself. I am so confused.....
I was trying to find an answer online, but I am still couldnt fix this. Please help!!! Thank you for your help my friend!!!!
I have sent my two files to your email address
