theSkyX format is incorrect
I used the editor to generate the ACP horizon editor, and I think it worked OK. However, when I generated the horizon for theSkyX, it is not in the correct format. I suspect it is in theSky6 format? It seems to be a binary file. TheySkyX uses a text file, similar to the text file produced by this editor (when saving to a text file, rather than theSkyX).
I was able to convert the text file format to theSkyX by hand, so everything is OK. However, that part should be addressed
