I had the same before, all I did was save as copy then edit.

Get this all the time in our work, people want copies of things that are locked.

Google for these:

Advanced PDF Password Recovery Pro
and
VeryPDF.PDF.Password.Remover

....between then they can remove the lock (try VeryPDF first, then the other if it still wont budge). Of course, try what sup3rc0w suggested first, works for some of them.
