Failed - Insufficient Permissions
I have been using Adobe Reader for many years. In the last week, a major problem has come up. When I try to download and PDF file, my screen starts blinking every 2 seconds and this goes on for a couple of minutes, then I get the message "Failed - Insufficient Permissions". I've tried un-installing and re-installing the software twice with the same results. For some reason I now cannot open any PDF files. Does anyone have a clue where I would start to fix this problem? Thanks in advance for your help!
