Uninvited guests.

I played this map about a year ago, and everything worked fine. I decided to replay it and downloaded it yesterday, but it's impossible to load – it crashes automatically. It crashes right from the very first attempt. Today, I reinstalled the game, added only the Russian language pack, and kept the rest of the client clean, but I still can't load the save file at all. I have no idea what the problem is; has anyone else encountered this? Update: I rushed and deleted the Russian language pack, and now it works. However, it's still a paradox why it happens that it's specifically because of it.
