Hi
Sorry about this but I had to roll back the update that I launched yesterday. While it seems it works for most users, it broke the game for other users. I'm working on fixing this but in the mean time I have rolled back the update.
The problem seems to be with the patch process in Steam. The build works locally but after updating, it looks like there are still references to old content which breaks the build.
Sorry about this, will try to get it working as soon as possible!
