I converted a drawing in PDF format to DXF by using Aide PDF to DXF converter. The file was converted but as I open the output in AutoCAD I get a following error:DXF read error on line 2275.Invalid or incomplete DXF input -- drawing discarded.Press ENTER to continue:I have used Aide output in Autocad before and there were no errors for those files. It gives the mentioned error for only few drawings which I recently wanted to use in my Layout. Any help would be great. Thanks.Best regards,Saad

Don't know.  Some things to try:
 
-Contact Aide PDF or see if they have a website that discusses error messages or common problems
-Can you "audit" a dxf file?
-look on line 2275 and see if you can spot an error
-Rather than convert to dxf, convert to a tiff and insert it as an image
