Organize pages feature not working

[Krystyne30]

This feature has stopped working. Every time I try it tells me "Unable to edit document". 

I used to be able to add pages to an existing pdf but now all I get is an error message. Is this a known issue?

Are you unable to edit/add pages to all documents or just this one?

For the record, what OS are you using (and what release)? What version of Acrobat are you using (and what release). Also, are you using the old user interface or the new user interface?

I have tried several different documents and get the same error (Error Occurred - unable to edit document).

I am using Adobe Premium for Google Chrome version 24.3.3.42602

I believe I might still have the old user interface as mine does not look like many of the screenshots I've come across.

My subscription is scheduled to be renewed at the end of May.
