I have an email with an attachment that opens with adobe. After I click on open it brings up a security alert that says "Your current security settings do not allow this file to be downloaded." I have checked and changed my security settings many times from the highest security to the lowest security and it won't let me open it. It only does this with file that are trying to open with adobe. I have also uninstalled adobe an reinstalled it thinking that maybe it was something with adobe itself. Nothing is working. Can someone please instruct me on anything else that I can try.
