So, when I opened the Security/Advanced Settings button it refused to let me continue until I turned back on Real Time Exploits, which I did. I then clicked on the Advanced Settings button and then Application Behavior/Restore Defaults button -- and I should add I NEVER played in those settings. The Restore Defaults did absolutely zip, and I clicked on Apply, which appeared to be live. I have no idea what occurred, the settings on the screen DID NOT change, however WORD and EXCEL now open correctly. I also was able to open the WORD document that was originally blocked.
