S!
Mission4today has all the patches you need. The site requires registering though.
They can also be found on this forum, although you have to scroll back the history quite a bit to find them.
Assuming your DVD version is 4.07, you need all of these 4.08 -> 4.09 -> 4.10 -> 4.10.1 -> 4.11. Mission4today has a mega patch up to atleast 4.10.1 which should make this a bit easier.
The clan? Who are you referring to? There are whole lot of squads talking on this forum. This is 1C company forum, host of the Maddox Games, the devs who made Il-2.
I for one belong to Finnish Lentolaivue 34
