Guys, I'd like to kindly ask you to not mix up free to use SSA by Olaf and pay-ware addon SimShaker Sound Module by Andre. That misunderstanding makes troubles for us, as developers.
Hundreds of Gametrix JetSeat owners use SSA absolutely free. SimShaker Sound Module is just an addon to bring new capabilities, but not the core software.
SSA can be used without Sound Module, but not vise versa.
