Hi!

I bought a game on Steam, it installs just fine, main menu shows as well but "New game" button does nothing. Other buttons work thought.

Now, every time I click on "New game" button there is a new entry in diagnostic log:

10:58:37:693 Runtime STACK RuntimeState_OutGame.End()

10:58:37:693 Runtime STACK RuntimeState_Lobby.Begin()

10:58:37:693 Runtime STACK The session has been created; opening the session in 'Single' mode (default)...

10:58:37:693 Session STACK [ILobbySlotProvider] SteamID is not valid: 0x0.

10:58:37:693 Unity STACK NullReferenceException: Object reference not set to an instance of an object

10:58:37:695 Unity STACK NullReferenceException: Object reference not set to an instance of an object

10:58:37:695 Session STACK SessionState_Opening.Begin()

10:58:37:695 Session STACK The session is being opened...

And near the begginig of diagnostic file I have something like this:

10:57:52:252 Default STACK Disabling GamesightManager since no steam id has been found

10:57:52:253 Default STACK Failed to initialize the Steam API; now running in offline mode...

I tried reinstalling the game, removing registry.xml, adding -compat option, veryfing game files, updating to Beta 1.2.20 - nothing works. It seems like some kind of Steam/ES2 communication issue.

Any help would be appreciated.

P.S. Steam is up to date.

P.S.2. I'm running on Mac OSX Sierra (10.12.6)

P.S.3. In the meantime I also reinstalled the Steam from scratch - same thing.

Thank you!
