I just purchased PDF creater under the impression that I could edit a document that is ALREADY a PDF file. Can I do this?
if you purchased PDFCreator then that is your problem. The tool PDFCreator from www.pdfforge.org where you posted this message is free/open source.
it can convet some printed outputs to PDF format.
it can not edit pdfs.
Thank yo so much for your reply. I will return the software.
