First off, Red Bow has finally released! Just in the nick of time too!
Second, I would encourage everyone to play Red Bow in Windowed mode. The reason behind this is that the steam overlay doesn't like to work properly in full screen but works fine in windowed mode. To access this setting, just run the 'Play Game Setup' when first launching the game. you can also change the window size with the options there to increase or decrease to your liking.
Thank you to everyone for being so patient and I hope you all enjoy the game :)
EDIT: I've added a quick patch update to fix the Russian language. It should all work now.
