Unfortunately since I am unable to repeat the issue, it's difficult for me to provide assistance. At this point, I would recommend downloading (or using "git clone") a new version of WRF and reinstalling it, and then trying again. If you don't necessarily need an older version of WRF (e.g., V4.0), I would recommend getting the latest version (V4.5.2). If you get past the issue, let us know how it was resolved.
