Yes, talking about game-specific music. I moved the "music"-folder to somewhere else and everything was fine. Now I moved it back, changed WMP to ffmpeg and everything was fine too. Then I changed it to WMP and Launchbox crashed. So it`s that. But it was WMP in 13.22, wasn`t it? Never had a problem with that (videos are there in details window but do not play automatically in my Launchbox, just music).
Thanks!
