A long time ago, Word Perfect had Word Perfect Documents. They may still have. Then Microsoft decided to have Windows Photo Documents. They were edited with Windows Live Gallery. Both used the .wpd file extension. My wife used both, too. About a week ago, someone figured it out, and MS apparently turned off wpd files, and those DIRECTORIES were no longer accessible. Nice job Microsoft!
After trying lots of utilities to delete the offending Windows Live WPD picture files, to no avail, I finally hit on using our Windows Home Server to do it. It doesn't recognize Windows Live anything, and I was able to open the directories and delete the 2 files. Hours wasted before figuring that out.
Hopefully Google will see wpd here and direct other frustrated users here to the solution: delete the offending modified files with an old computer/OS. Never use Windows Live Photo Gallery to modify anything again!
