For some really weird reason, when I start the game's .exe on this version, all of the buttons are unresponsive, and I literally have to ctrl+alt+delete just to quit out of the game. I tried both .exe's, and I tried running them as administrator - nothing worked. I'll try downloading the game again - fingers crossed.
EDIT: Okay it turns out that saving over the last version made it unresponsive - I unzipped the game into a new folder, transferred the saves from the older version, and it seems all good. Phew.
