When I run the Statistical simulation example I consistently get a windows error message saying that stepwise_wipp.exe has stopped working. I'm forced to close SAM through the Windows Task Manager.
Could you provide some more detail about your analysis? What performance model and financial model are you using? What variables are you choosing for the statistical analysis?
If possible, would you mind attaching a copy of your SAM file (.zsam) to your original post, or sending it to me via the contact page?
