Visual Studio 2013 Express for Desktop on Windows 8.1 x64, using Help Viewer to read MSDN library.
Recently help viewer Manage Content feature updated document indices, and previous content vanished. e.g. Desktop development, Web development. I also see Windows Debugging topic under Recommended Documentation, which is odd. I've run Repair from Control Panel several times, changed location Help Content folder on disk, re-downloaded all content, nothing changed. Anyone else have this problem?
