We have a PDF with a number of file links to swf files. We used to simply copy the PDF documtent with all of the supporting swf files and as long as they were all in teh same folder things worked fine.
We would access in Acrobat: VIEW - TOOLBARS - ADVANCED EDITING
Once the advanced editing toolbar was visible - click on the 'arrow' and then right click on the BUTTON in the PDF document - then - select properties - action - open a file - at which time Acrobat sends you to the directory on your computer with all of the associated files.
The difference now is that the web site where the PDF documents are accessed is more secure and requires a specific path to the swf file. Can not find a way to input the direct path to the file online - within ACROBAT PROF- which needs to go in front of the document name.
Hope this makes sense... Please let me know if you need more details.
It may be a questions of permissions associated with your production box/OS.
In order to use Acrobat Professional for editing the PDF(s) and to establish the target *.swf files out on the network share or intranet web server you will have to have read, write, edit, delete permissions to the appropriate directory/directories and to the files. Without that you can look but not touch (if you've read, read/file scan permissions).
If you are the one who actually transfers the files to their production location then you've the requisite permissions.
If someone else does the transfers then it might be that you do not have the requisite permissions with the server(s) OS.
That you can no longer do what you've done in the past is strongly indicative of an access permissions issue.
Be well...
