I would suggest that you get the 2.3 developer version of the game. The 2.2.1 just stops after a certain point and the dev version is much more polished in every respect. There are links to ready made installers in the Windows subforum.
The devs are not going to fix problems with 2.2.1 anymore, because most things wrong with it have already been taken care of in 2.3. The most glaring ones anyway.
