Hi, im taking a look at the msafluid library:
http://www.memo.tv/msafluid/
Im try to execute the MSAfluidDemo.pde. The code is pasted below. I´ve made a folder called msafluid inside another folder called libraries inside the sketchbox folder as I have done with others libraries that worked correctly. I´ve put the msafluid.jar inside msafluid folder, and MSAFluidDemo.pde inside a MSAFluidDemo folder inside scketchbook.
I receive a message " the mackage msafluid does not exist. You migh be missing a library"
I´ve executed MSAFluidDemo.pde from diferent places with the same result
This is the code:
