Heartrate returns 'null' in simulator with a FIT file loaded

Hi all,

I'm writing an app that should show the heartrate on the mainview. I have uploaded a FIT file from a recent tennis match and this loads succesfully. But when I play it, the screen of the simulator doesn't update (also the clock doesn't seem to update until I press a button?) and the heartrate value remains null.

I have updated to the latest SDK 4.2.1. Anybody have any tips on this?
