Did you download the Russian version of the 4.08 patch by mistake? We found a Russian version of v4.08m and uploaded it at M4T recently so if you downloaded from us there is a possibility that you got the wrong one.
This was not recently by any means, I've had it for a few years. So if I did an over-write with the non-Russian version I'd be OK?? Funny, I had a standard 4.08m version with an English splash screen for a long time but lost it somehow. Now I'm left with only this.
