AutoCAD Error

[MBIpdf]

I have crashed a couple times in making pdf's in Autodesk's Architectural Desktop 2004 software. The error was:
Unhandled Access Violation Reading 0x0030
Exception at 30h

It simply kills my AutoCAD session (running XP Pro)

I have had problems with another pdf driver killing my CAD, pdf-xchange as well.

Any idea as to why the pdf creation would kill my CAD?
Any similarity between the 2 programs?

:confused:

When in ADT 2004 on a Layout, I plot a sketch to my printer, then I go to another Layout and try to PDF the 2x3 drawing and I crash. It seems to be when going from one tab to another. :(
