Yesterday and week before I've been using the free acrobat reader with no problem. Today, any pdf I try to open gets an error saying there is a problem with protected mode and the open fails. I want to download the free adobe reader, which I thought was my default reader but today opening a pdf open the pay-for reader. Every site that I try to download from requries me to download some other software before I can download the reader. I don'twant any other software, I just want the free Adobe reader.
