I just purchased Sins of a Solar Empire online an hour ago and I'm going through the tutorials to try to wrap my head around some of the most important aspects of the game.

I'm stuck in the second tutorial though - Basic Logistics. A few steps into it I'm asked to select a construction frigate (specifically "select it" - even though there are actually two) and build a defense platform. I go ahead and do that, but whether I build one, two or six the tutorial doesn't continue - no "OK" button to click, it just keeps showing the same message on the screen.

I've tried restarting the tutorial twice, but it makes no difference.

Am I missing somewhere here (if that's already the case, I guess I really do need those tutorials ), or is this tutorial bugged or broken?
