Please make sure to read the important details in the ReadMe document about what has been addressed and important installation notes.
Every time you experience an “unplanned exit” from AutoCAD please make sure to send in a CER report as this is where we get a great deal of clues on the problems details and possible methods to fix it in a hotfix or service pack.
Cheers,
Shaan
