Crash to desktop upon starting game

I just bought Gratuitous Space Battles in on steam in the ‘Indie Air Pack’.
When I start the game, it crashes to desktop immediately, giving me the message “GSB.exe has stopped working”. This happens immediately, only showing the very first title screen.
The ‘additional information’ is as follows;
