I've got some PDFs that are several years old. I'm not sure what program they were made in originally, but it may have been PageMaker. When I open one of these files in Acrobat X Pro, the content edit tools are grayed out and I can't use them. Acrobat does seem to recognize the text as text, however, as I'm able to select text in the usual manner. Does anyone have any ideas on how to troubleshoot this? Would it even be possible?
I'm using Acrobat X Pro on OSX 10.8. Thanks.
