Today, I've encountered an issue which prevents me from launching the game.
After launching the game, the usual steam window appears :
launch.png 13.9KB 1 downloads
Message translation : "Preparing Dreamfall Chapters launching..."
Then, after a few seconds, the dialog closes. Few seconds later, it reopens, then closes again, and so on...
The issue occurs both when launching from the steam menu and from the shortcut.
When closing manually the dialog, sometimes, it closes definitely, sometimes, it still reopens after.
I don't know whether it is a DFC bug or a Steam one.
Restarting Steam doesn't fix it. (I'll try restarting the computer and keep you updated if it does change it)
