If you're having trouble with the above fix, you can try using a batch (.bat) file to automate the old date-change workaround. Details here:

Basically, you copy/paste the script into Notepad and save it as a batch (.bat) file, which you then use to launch the game. The script changes your system date to October 2nd, launches the game, and then reverts to the correct system date when you're done playing.
The setup is a little more involved than some of the other fixes, but the end result is that I can simply double-click an icon to start the game and play normally.
