Simulation: "Data not available" Error

[takedownca]

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. If I delete the study and start over it usually still occurs. 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.

Turns out the max frequency limit was lower than the first mode.
