Unable to copy pages from Authentisigned PDF to new PDF Document object

I have a pdf document that has been signed via Authetisign.  
I need to make some modifications to the document, knowing that this will break the security seal.
To expedite the processing I am splitting each page of the document into individual pages.
As I attempt to copy a page from the signed document into a new document I receive an error I can not find any documentation on.
Please advise how to solve or circumvent this error.
