Searching the regestry, i found it under:
HYKEY_LOCAL_MACHINE/Software/Adobe/6.0/AutoCAD/2000/Loader
Name "Module" Type "REG_SZ"
If you rename the file PDFMAcad.arx found at:
C:\Program Files\Adobe\Acrobat 6.0\PDFMaker\AutoCAD\2000\PDFMAcad.arx
Autocad loads an empty menu at that location.
So i deleted the regestry entry, and that solved the problem.
CAB
You can also uninstall that portion of Acrobat. Under add/remove programs,
the uninstall for acrobat lets you change the install.
jsut remove the autoCAD portion in the creator.
you will need the CD/Files you installed with though
