My drawing cannot be opened

CAD tips: Error in graph header, line 1. C:\Documents and Settings\Administrator\Desktop\Temporary Folder\mengjia.dxf is not a valid DXF file The DXF input is invalid or incomplete -- the drawing was discarded. I used CAD's repair command to repair it, but still got this prompt. Can such a picture be repaired using other methods?
Just open the original CAD drawing ending with dwg, create a new CAD drawing ending with dwg, copy the contents of the original drawing to the new drawing, and then save the new drawing as .dxf. Give it a try.
The CAD file format is wrong and should be changed to DWG format in the properties.
Is it a version problem? Try changing to a higher version of CAD
Thank you for your enthusiastic help. The picture is an email. I can't find the original dwg drawing. I have tried changing the suffix. What's frustrating is that the updated CAD is not available yet... Mine is already 2009.
