Navisworks 2010 Manage Error Loading NWF "Contents Are Corrupt"

[mdlamarra]

When tried to open up my model (.nwf) file, I received this error message:

“Couldn’t load TUCHQ.nwf because the contents are corrupt”
“C:\Documents and Settings\myname\Desktop\Navisworks\TUCHQ.nwf”

I opened each individual (.nwd) file that had been appended into the (TUCHQ.nwf) file, and they all opened without any problem. I tried to recover the backup files that were saved into my “C:\Documents and Settings\myname\Application Data\Autodesk Navisworks Manage 2010\AutoSave”, but they were also corrupt.

The beginning of yesterday, I was able to open the (TUCHQ.nwf) and I clashed approximately 70 different clash combinations, and created saved viewpoints during this process. I was saving the (TUCHQ.nwf) often to my desktop throughout the day, and at the end of the day I decided to copy the entire folder onto a thumb drive, and then finish creating the viewpoints at home on the laptop that I would be using for a meeting today (that never happened). I copied the entire folder onto my laptop at home, and when I tried to open the (TUCHQ.nwf) got this error message. I then called work, and my coworker went to my pc’s desktop and tried to open the (TUCHQ.nwf), and he also received the same message. I lost approximately 10-11 hours of work yesterday, and I am desperate to recover this (TUCHQ.nwf).

Is there anything that I could do to recover this (TUCHQ.nwf), or resolve this error?

If you have Subscription, I'd recommend opening a critical tech support request to have Autodesk fix the file if possible.
