That sucks because the campaign is the only thing I play IL 2 for and how do i play IL 2 online? When I click Multiplay, it takes me to local not over internet

Donwload and install this small software, is called hyperlobbby. Almost everybody who plays IL-2 on multiplayer use it.

Connect selecting IL-2 Sturmovik 1946.
There you will see lots of dogfight servers, some with patch 4.09, and some other with mods. You will to make sure to select a 4.09 to fly.
The rests i hope you will figure it out by your self :).

And its done!

Tacky, the multiplayer in main menu is for LAN and known IP addresses only.

Most people use the Hyperlobby: http://hyperfighter.sk
