Simulink cannot load the initial SimState

Hi everybody,
I've got a problem using SimState. My aim is to run a simulation stepwise to be able to run various simulations for the next timestep with different parameters.
My problem is, that Simulink just throws the error "Simulink cannot load the initial SimState because the model, ''model_name', was changed after the SimState was saved. Run the simulation again and resave the SimState."
I already compared the checksum between two simulations regarding (<http://de.mathworks.com/help/simulink/slref/simulink.blockdiagram.getchecksum.html>, and the "slAccelDemoWhyRebuild"-example).
Seems that there are no differences in the checksum and also the models aren't rebuilt each restart of the simulation. I'm using Matlab R2014a, fixedStepDiscrete-Solver and the "normal"-running mode. Do you have an idea how to solve this issue?
Thanks a lot! Felix

I could establish the problem by now. Matlab 2015a was able to show the differences in the checksum caused by the integration method of the used discrete-time integrators.
The "Initial condition setting" has to be set to "State (most efficient)".
