Steve, I managed to get 4.02.00.00 to work by doing a complete reinstall. Some things I discovered that may be of help to others.
1. After copying my saved games, I tried reinstalling from the original disk to save on downloads/time. Although I got version 1 of the game, I had trouble updating it, so I ended up downloading MWiF from the My Games page or whatever it's called. This process could be tricky for newbies, because it's in two parts and the installation stops and requests the second part, which you have to extract and tell it where it is.
2. For me, the game only seems to like being in the folder it wants on my C drive. Whilst in ran fine on my F drive, it wouldn't update to 4.02.00.00
