I have windows 7 and my system became unresponsive, so I restored it to 3 days ago. Now I am all of a sudden not able to open my PDF files. I uninstalled/installed Adober readed and still get the message that "These files can't be opened. Your interned security is preventing one or more of files from being opened". I followed the instructions for resetting the internet security options but still see the same messsage. I can see the file icon but cannot open any of the pdf files, even the ones from way back.
Software/Hardware used: Windows 7, Adobe reader 10.0, IE 8
