Autodesk released a "new" version of the Survey Hot Fix for AutoCAD Civil 3D 2013 on 5-23-2012.
Substance or Packaging? You Tell Me
This Survey Hot Fix is pretty important as it makes Figure edits possible in 2013.
Without it I figure you are simply out of luck.
There are both 32-bit and 64-bit versions of the .arx now included in a single download .zip file.
Use the Right one Not the Left one
You must manually replace the existing file in your AutoCAD Civil 3D 2013 install folder.
The first version of the Survey Hot Fix was initially released last month and at least my 64-bit file was named incorrectly.
