After launching ivmpGameLauncher.exe and trying to connect to server, nothing happens (except console box that appears for 0.3 seconds). Task manager shows that game is trying to start, but process is ending suddenly. Singleplayer works fine, EFLC version is 1.1.2.0. Tried many things, but nothing helps.
Here's launcher.log (there's no client.log):
