Hi Tatyana, to use Rescue3DMFile in Rhino, type in that command name and then pick your file, then at the first prompt pick "Recover" and at the next prompt push "Read All" and that seems to find a whole bunch of stuff in there.

I did a quick run under the debugger and one warning message is printed that there is a CRC error in the file - that means that a checksum that was recorded when the file was written does not match the current contents of the file, usually that means the file has been damaged or garbled in some way.
