Hey guys! The new Rubber Ducky updates seems to be having issues with antivirus software, particularly Avast. If the game doesn't launch after you click play, then do this:
1) Restart your computer
2) Turn off and file shield or real-time protection for your anti-virus
3) Run the game as an administrator
I'll try to figure out why these programs are having issues and release a small patch to fix it. Thanks!
EDIT: For now, if the game isn't working for anyone that it was, I added a launch option to use the past version instead - it won't play the DLC, but it still has almost all of the other content!
