I am going to try and make some clearer instructions as opposed to whats on UBI forums right now.
1. Download and install Ubi game service is you dont already have it installed
http://gamingzone.ubisoft.com/packages/GameService.exe2. Download
http://www.rmutt.netfirms.com/FBServer.zip3. Create a folder in your IL2 FB dir called /launcher
4. Extract the FBserver.zip into your /launcher folder
5. Double click on Fbserver.exe goto options/preferences and IL2 FB game path (box at the bottom of window) to the orginal il2fb.exe in your IL2 install dir. You will have to type this in manually. When you are done click save.
(by default: C:\Program Files\Ubi Soft\IL-2 Sturmovik Forgotten Battles\il2fb.exe)
5. Rename the FBserver.exe in your /launcher folder to il2fb.exe
6. Go into your il2 fb dir and rename your il2fb.exe as il2fb_temp.exe
7. Now, start HL and hit connect, it should tell you that it cannot find the il2fb.exe. Point HL to the il2fb.exe in your /launcher folder and press Save (not search).
(by default:C:\Program Files\Ubi Soft\IL-2 Sturmovik Forgotten Battles\Launcher\il2fb.exe)
8. Now go back to your original il2fb.exe that you renamed to il2fb_temp.exe and change it back to il2fb.exe.
Thats all there is to it. A word of caution. Just pay very good attention when you are typing in and it will go smooth.
Hope this clarifies this. Its not too hard to do. Most of the problems people are having when doing this is typos.
Good Flying
