I had the same issue and what worked for me in steam was to click "properties" on the factorio game, then "betas" and revert from what was "0.15.x" to "0.15.9" and it loaded properly. hope this helps.
I´m waiting your update to 0.15.10 because i can't continue playing with my big factory map. I can´t revert to 0.10.9 because other mods make use of the new use of steam. Thanks for making this awesome mod.

And dont forget to let me ideas for more mod content.
Have fun guys
