The Steam update was late because I was away for the past two days - it should be live now.
Thanks Ashley, now it is updating, but not properly.
"Failed to Start the Game (Missing Executable)"
When unselecting beta opt it works on r139, but then again when opting for beta it doesn't work anymore. It seems to download the update OK but there's something wrong with it.
I tried to delete the appcache folder from Steam and start all over but no luck :(
