HOW TO FIX: 1) go over to your User’s Library/Preferences folder. Update 05/20/15: After running all of my tricks listed in this article, I found one that isn’t listed that seems to have corrected the issue. I will report back on other ways to resolve.

It didn’t matter if I opened a document directly or one of the Office applications, within a few seconds, the Office App would crash.
