I recently got a friend interested in trying out FSO, and we're having issues. She installed FS2 from GOG and ran the FSO installer, and now we can't get the game to actually launch. When she tries, it complains that "FS Open couldn't generate a flag file", and fails with status 255. I attempted to have her generate an fs2_open.log file, but the "Advanced Settings" tab is blank aside from the same complaint about a missing flag file. We followed the rest of the steps anyway, but there was still no log file.
At m!m's suggestion, I had her run a debug version of the launcher, so we do have log files from that: http://tinyurl.com/xenodropbox/wxLauncher.log
, http://tinyurl.com/xenodropbox/wxLauncher (1).log
(the former is from yesterday, the latter is from minutes ago).
At this point, I'm out of ideas. She's running OSX (version 10.9.5). I'd call myself technically adept (though fairly unfamiliar with OSX), but my friend isn't, and she's also in a different state right now.
