fbx importing - an ongoing battle

i might be going crazy, but i swear that fbx files that were able to import previously have stopped working. my general workflow has been to use autodesk’s fbx converter and conform any files i receive to fbx 2011, and then bring into blender. but now even that seems to fail on both blender 2.74 and 2.75a. mercifully i was able to make it work with the latest release candidate for 2.76… but i swear it was working with earlier versions (literally the exact same fbx file that was working a day earlier)

anyway, long story short, i hate how finicky fbx is!
