Failed to Launch, #10006 Invalid Checksum???

[smink1701]

Game will not launch and getting this message.  Any help would be appreciated!

Do you normally launch the game using the .exe file? If so then try using the launcher as it may need an update

I get the "#10006 Invalid Checksum" message if I try to play IL-2 offline just after an update completes in the launcher. If I click the green "Enter" button (for online) first, then I can exit the game, restart it, and click the "Offline" button.

 

Note that this issue is also discussed in this recent post.

I can usually launch the game with bin/game/IL2, IL2 Launcher or IL2 Restarter.  All will take me to the start screen where you select online or offline but then I get the error message.  If I try to start game with Launcher, I see the spinning blue wheel for a few seconds and then it goes away.  Arg!
