accidentally locked file
Hi. I somehow accidently locked a pdf file in Adobe Reader Ver 2015, but never assigned it a password. It now has a lock icon next to it and I can't open it or even delete it! All I want to do is delete it but when I try it says I need Administrator permission. I am the administrator but also went and tried to change the file to where it was accessible to useres and everyone, but still no luck? Any suggestions?
