OFFLINE mode / "Cannot exit offline mode due to hardware ID change"
With DCS World 2.5.1 we have implemented new OFFLINE mode.
To transfer DCS to OFFLINE mode, click on the antenna button in the top panel of the main menu. This can be done ONLY after successful authorization. You cannot enable OFFLINE mode unless you have an internet connection first.
User can turn on OFFLINE mode that allows the game to be used without internet identification and without a time limit.
If you don't want to play Multiplayer game, no need to enable OFFLINE mode.
Note: user must turn off OFFLINE mode on the same PC*. OFFLINE mode cannot be turned off from another PC even with the same user's login.
* on the same PC - it means exactly the same for both hardware and software. For example, changing BIOS or reinstalling Windows in offline mode will not allow you to log in.
The mode is unlimited in time, thus all network services (Manager of Modules, multiplayer, news) will be inaccessible.

that means you are no longer able to play DCS.
