Your file is pretty broken, it lacks the BLOCK_RECORD TABLE for the UNFOLD block. You can try it with Autodesk DWG TrueView it will show the same issue and will discard the drawing. Also, the entities of the UNFOLD block do not have handles assigned.

A workaround for these problems is possible but for more complex drawings it might have unexpected side effects. In any case this does not forgive the program that created the DXF for doing such a poor job.

This second file you posted is new and different from the one in your first post. In this case the file has been saved as a pre-AutoCad2000 version. This library is only compatible with versions AutoCad2000 and upwards.
