I have the same issue. Until today the game started correctly, but now only some seconds checking with updater and then it closing. 0 error message or something. Restarted the process more times nothing changed.
Deleted the battleforge folder in documents changed nothing, but were a difference which i dont know how works... maybe the part of the problem. Before i deleted the Battleforge folder in documents it had config and keyBindings XML files and tutorials, trade, storybook, save, replays, randommap, loadingscreenaudiostore and Diag folders. After i deleted Battleforge folder and restarted the updater (naturally crashed again) it only had the config XML file.
