Blender report error during loading: DNA block missing During a rendering I had a voltage drop, my UPS didn't work properly (damn, but the battery is new!) so PC shut down.
I was more or less quiet because I saved a minute before start rendering, but when try to load my saved file blender report an error never seen before:

Loading: "E:\path where is the file" failed: failed to read blend file "E:\again path where is located file": Missing DNA block

It is the same, if I try to upload file from my saved folder or I try to recover from autosave tmp folder, or if I try to recover last session or quit session.

The file is not empty, is 66mb

I can load any other blender file without problems.

Any idea? Did I lose the file?
I found a solution if this happens. go to recovery and save the files again . Need some luck too :)
