I was playing a normal sandbox game and realized I wasn't logged in to the service that tracks our achievements, etc. (Don't know what it's called)

I figured I should log in so I could claim any achievements I happens to unlock, so I logged in, the music stopped for a few seconds, then started again, then the game crashed. I usually log in at the main menu, and this is the first time I played since downloading the 1.01 patch, so I'm not sure if it's related.
