Error while copying .dxf data during Dataset Import

Hello,

I was attempting to import a .dxf file I generated from an existing .dwg file, and I ran in to this error message:

Unfortunately I could not find any other indication as to why this error was generated, so I tried one of the fixes for general problems with .dxf files that I found on one of the Bentley Forums: saving the .dxf file as an older file type. I tried saving as a 2010, and 2000, .dxf file and neither worked, the program still gave me the same error. Has anyone else run in to this? Does anyone know any other possible solutions?

Thanks in advance.
