Rhino ERROR (unreadable geometry object)?

Hello there.

I need some help here please.
I receive this unlucky error…

I dont know what happen because what i am do is open a Rhino file where, before, i made some complex 3D model with all interior objects and i cant believe that its missing an important part of that project??!?? :frowning:

This is a really strange situation, because i only have that file. And i erase all grey rhino icon file that i suppose rhino keeps saving for protection (autosaving). And most of all, that work was made in Windows 7, and now i am on a fresh and clean install of Windows 10.

The other strange situation is that file still have the same size like it before.
Is it possible to recover the missing part?
I have made the “Rescue3dmfile” command, and it show a big list of codes that i do not understand. But in the first line it say:
“To find damaged parts of the file, search for the word “ERROR” in the following list.”

What can i do?

Ups, i think i found that missing parts.
I have choose the recover and Rhino read all errors. But now it all became in the same layer!!

failed to write bt.dinf to sysconf

Is this in any way related to Rhino?
