Having no issues with main game but when trying to start a new sandbox game it allows me to select the map and settings but freezes on the loading screen. The loading circle in the corner will complete about 3/4 of the circle then freezes. Music will continue to play without issue until the song is over, then silent.  

After closing game manually and re-entering into the same sandbox (which has a little red triangle with ! in it) it takes me to the main maps overview, but won't let me unlock any map as I only have 5 kudosh. 

Thanks :)
