Try removing all old save files from the previous version from their folder. The game scans save files, and if it doesn't find what it expects (like the new races added in this version) or if there is one save file with what the game considers corrupt or incorrect data, it just locks everything.
I am also having problems with the loading of the game. No character sprite and icons frozen on screen clicking them does nothing they seem misplaced, screen after starting new game
