Acrobat 8 w/AutoCAD Mechanical 2009

We just upgraded from AutoCAD Mechanical 2006 to 2009. I've loaded the pdf maker (PDFMAcad.arx) for AutoCAD 2007 as this is the latest version Acrobat 8 supports.

The resultant PDF created from a dwg file using the pdf maker has missing information, it seems to be just text from attributes, i.e. in the title block and bill of material. All other information contained in the dwg file is showing up in the PDF.

We never had any problems using Acrobat 8 with 2006. I realize Acrobat 8 doesn't support AutoCAD 2009 nor does Acrobat 9, however I thought I'd post my problem just in case it's a simple setting in Acrobat that I'm not aware of.

Thanks,

Vicki
