Please, please help.

My Petrichor crashes.
When I click to open the sample �box2.3DS� file or
If I click on the �update position� button.
Below is the error I get


Petrichor.exe has generated errors and will be closed by windows.
You will need to restart the program.

An error log is being created.

I am using
Petrichor 60675
GE ver 3.0.0693 build date Oct 18 2005

I have some knowledge in LISP and VBA programming so if I knew how to convert N,E to lat,lon I could write code in AutoCAD to output a 3D object.

All the same, rather than recreating the wheel, if anyone can help me to get Petrichor working I would appreciate it.
