A little help please?

[P-51]

Hello guys!

I've been around these forums for a little while. Albeit on the Birds of prey section.

Right to my problem:

I recently got 1946 from steam, it downloaded and plays perfectly. However, it is version 4.09m. I want to play across the net which means I need to update. I get that bit.

The crux of the problem occurs when I download 4.10. I load the game and nothing has changed, on the loading screen it still says 4.09m

Now, I don't know how to get it to work. Do I need to download the 4.09 skins update before 4.1? Am I letting the .exe run in the wrong place (to the 1946 folder)? Any help will be appreciated!
