I keep getting this error message when trying to show a chart in certain studies. Once I start getting the error, it won't go away for that study. Sometimes if I delete the study and start over it fixes the problem. I'd like to know what the root cause is so I can avoid this in the future. The results (CWR) file is present and of decent size. I'm using SolidWorks 2009 SP3. Thanks for any insight.
