EHM The Blue Line

Hi! Not really sure if this is the right thread...Installed the 1.5 beta, started the new game...now, when it comes to actual games, I cannot switch from "play" to "view" or whichever status it is that allows to quick sim and just see the results. The "play" button is gray all the way.
Tried digging for solution in preferences, but could not find one.

Can anyone please help?
