Pure virtual function call

Clicking okay then shut downs Inventor loosing any work not saved.

I've tried googling this to find a solution / work out what we were doing wrong but I can only find discussions for this in AutoCAD. Could someone please tell me why this happened / what caused it to happen and if possible what to do to prevent it from happening again?

At the time of the crash I had one .iam drawing open (186kb), one .idw open (9,035kb)

(And the BBC new website I was reading when it crashed).

Could you attach the dataset here or send it to river-yijiang.cai@autodesk.com? And do you submit the CER report? 

[#3]

Could you please explain what you mean by dataset? I keep submitting the CER report.

Dataset means the models that you used to have this issue. And could you let us know what email address you used to submit the CER report?
