You left before I had a chance to reply and/or help in the lobby.
Ikinz alerted me about 4 minutes after you left. Your issue is simple. The lobby was just hanging up on grabbing a dependency. It's an easy thing to fix and wouldn't ever happen again. I am not one of the lobby developers, but ikinz is.
He could have helped you out if you had stuck around.
He said this to me after you left:
ikinz | [Evo]Forboding_Angel: this guy just made me realize how confusing it must be to try to play evo for the first time if you're not familiar with spring
At which point I explained what the problem was (it's a lobby issue, not a game issue).
To directly answer your question, the lobby IS an installer. It installs maps, game, and engine for you automatically.
If you log in again and say [Evo]Forboding_Angel in the chat, I will get notified. I can solve your issue in 20 seconds (by making the lobby grab the dependency manually) :-)
