Import the project into 1.2.0 RC1 and run the scenario. I see this exception:

java.lang.NullPointerException
at org.eclipse.stem.solvers.rk.impl.RungeKuttaImpl.step(Unknown Source)
at org.eclipse.stem.core.scenario.impl.ScenarioImpl.step(Unknown Source)

Fixed. EMF problem, the "initialized" attribute of the solver should be volatile and not persisted. Also fixed the downloadable scenario to correct this.
