I'll forgive their insolence this time, but next time they ought to ask me if I would like to download the game in the background. I could understand stopping the download for online games, but I'm playing single player. I was able to find and check the box for allowing downloads during gameplay.
Fenixp: You should be able to enable in-game downloading somewhere in the settings. Worst case scenario, after launching the game, just re-enable download either by alt+tabbing out of the game or by shift+tabbing into the Steam interface if you have it enabled. It's disabled by default because people are apparently too thick to pause downloads when playing online games and then bitch about performance
