Well the title pretty much says it all someone have forgotten to update the "JigLibX Xbox 360.csproj file"
so it doesn't have the new "CollisionSystemSAP.cs"
And when i add it manually add the file and run the project on my xbox the i get an error like this
An unhandled exception of type 'System.InvalidProgramException' occurred in JigLibX.dll
Exactly when the first collision takes place
actually that error seams to appear with all of the different CollisionSystems
I managed to get rid of the error by changing to
world.SolverType = PhysicsSystem.Solver.Normal;
