Welcome mozgovoy to Subsim.
Did you get the patch for Silent Hunter 3 version 1.4?

If your running Vista when patching right click and run under admin.
The patch has an error showing version 1.3 thats fine.
Once done then I suggest downloading a super mod example GWX 3.0

To get started. They have a huge manual to read which will give you all the secrets of the game plus the how do you do this and that.
Later when you have more experance then try other mods.
Happy new year and drink responsibly.
