broken pipe on playback

If I run a particular test, it keeps failing at the same spot.  I've rebooted several times and that has not solved anything.  I did do a shutdown and restart and it did work once, however, since then, keeps failing on the same step.

Product Version 2012.2.1420.0
Windows 8.1, IE 11
