Brain Explorer 2 crashing when visualizing human gene data

Hi Community,

I have been trying to visualize human brain gene expression data in the Brain Explorer 2 desktop software (Mac). I launch the explorer from the human microarray page for a particular gene (e.g. GRB14, see link below). However, the app crashes as soon as it opens without visualizing the gene expression, with the following error message (see below).

I’ve tried 1) redownloading the app, 2) tried to visualise other genes and 3) using different machines (with OSX El Capitan and Mojave) to the same effect.

Does anyone have any fix for this? Thanks!
