Steady stability VSPAero run produces a blank file?

[skyc...@gmail.com]

Hello,

Recently I have been unable to get VSPAero to produce a steady stability (.stab) file with any data in it.  When I run a stead analysis, it generates the necessary data which is viewable in the results manager, but the file output is blank.  Any one else running into this?

Thanks,

Bryan

Noticed that there's an error saying it can't find a specific control surface in the control surface group that I've selected, so I'm guessing that's the issue.

Tried to troubleshoot but it appears that VSPAero doesn't like one of the two sets of control surfaces I have in the control group.  If I get rid of it, then the analysis runs.  It keeps saying it can't find the controls in the control group, but when I run it with the stability analysis off, it runs fine and recognizes the problem control surfaces in the control group and deflects them for the analysis (at least it visualizes them).
