java.lang.NullPointerException

I was reading up about FSAF.

FSAF (Fast subband adaptive filtering) measurement

I took FSAF, acoustic, and regular sweep measurements. Distortion levels differ by a factor of 10. There are several differences. The stimulus is not the same Sweeps have low crest factor (the peak is only 3 dB above the rms level) so for a given rms level the signal peaks are much lower than...

I downloaded "FSAF 2.mdat" from post#27, opened in REW v5.31.3, clicked the "Distortion" tab, REW crashed.
The other tabs seem fine, only the "Distortion" tab would trigger the crash.
