Yeah, I can now quit Steam and the game still works. The issue seems to have been fixed.

This is really frustrating... it is possible to get the game to work again, but the solution ain't pretty. Here goes. As Mopizappuu and ElPee said before me, the first step is to delete Steam from your Applications folder, then delete the Steam folder on [username]/Library/Application Support After that, download Steam again. Do not, I repeat, do NOT let Steam update from now on; I'll elaborate in a bit. Download Avernum again. Halfway through the download, I got this prompt: "Steam - Self Updater A Steam client update has been downloaded. Would you like to restart Steam now to apply the update?" Close that window. You may get another message soon after, which says: "Steam - Restart required Thank you for participating in the beta on Steam. The beta has now ended - please restart Steam to return to the current release." Hit Cancel. Now, you're free to play Avernum: EftP again. However, there's a catch. The game will only launch properly from Steam. From this point on, you cannot quit Steam. If you quit the Steam application, then the next time you launch it, it will automatically update at startup, and you won't be able to launch Avernum again. If that happens, you'll have to repeat this whole process.

I uninstalled Steam, deleted its folder in Application Support, reinstalled Steam and Avernum: EftP, and it did NOT fix the problem for me. Still won't launch properly.

Yeah, I'm pretty sure you guys broke your game just now I'm using OSX Snow Leopard (v. 10.6.8), and I've had no technical problems with Avernum: Escape from the Pit so far. Then today in the morning (April 20), it just stopped launching. I tried launching it from Steam, but it didn't work; so I restarted Steam, tried again, still no go. Then I restarted my computer and tried again, and still didn't work. Then I tried to run the game from [username]/Library/Application Support/Steam/SteamApps/common/avernum escape from the pit (where Steam stores the game on OS X), but I got the same deal: The Avernum: EftP icon bounces a bit on my dock, then the application just quits. Trying to load it this way, I even got a "Avernum quit unexpectedly" error message. Then I figured my installation might be corrupted, so I backed up my save files from [username]/Library/Application Support/Spiderweb Software/Avernum Saved Games, asked Steam to Delete Local Content, re-downloaded the game, and it still won't launch. I once again tried to restart Steam, launch the game manually, restart my computer and try again, but to no avail. Please fix this!
