Hello, I am playing the Mac demo in STEAM. I passed Mission 3: it says "Well done, agent. You have successfully completed this mission." Below this, it gives me an option to "Research History". I do this, and it gives me an option to review Missions 1-3; it will not let me go forward to a 4th. The Globe and Grid buttons (bottom, center) are still locked. I click on the STAR or MISSION tab, and it tells me I am "Agent Class: Agent". I click "Open My Mission" and it brings me back to MISSION 3!!! I CANNOT PROGRESS! I've tried re-doing the level several times, and the same thing happened. I tried restarting my computer and the game several times, and the same thing happens. I won't be able to continue playing if I do not get help with this.
