Battle.net has word that a new patch is now automatically available for Starcraft II: Wings of Liberty to update the RTS sequel to version 1.01. The new version optimizes campaign saves, and fixes an issue with sound not playing on some 7.1 systems. Thanks Big Download.
Wow, it sure did. All my autosaves and manual saves disappeared, so all progress in the game is now gone. But hey, I still can see my achievements. :-(
