After a bit of searching on the web and test other Simulink models I found a 'Single simulation output' parameter in the 'Configuration Parameters' Menu, and this was set to on. I unchecked it and now everything works fine again. Matlab crashed after starting the Solver Profiler, and then the single Simulation Output file appeared, maybe this has something to do with it?
