Just like I can't fix corrupted Excel spreadsheets, I neither can fix corrupted PDF files. By the way, if your PDF requires a password just to be read, I can't help you crack it. However, if you can't copy and paste or print your PDF (but you can read it), I wrote an utility you can use to remove those restrictions: http://www.ensode.net/pdf-crack.jsf.
