Yeah, the dude uploaded a standalone version the same day I installed TTW =D
Anyway, I thought it might have been the timescale thing, since GNR also gives out occasionally when I change settings related to that, but I reset it to the default 30 both in Project Nevada and Imps Needs, then saved and reloaded the game - everything was still silent (except GNR). So I really have no idea.
And to make this more confusing, Outcast Signal works fine, no matter the timescale setting... =/
