Impossible to play!

I’d post a good review of the game. But now every time I play in Multiplayer mode, I can’t move, and my Monkey get disconnected saying Try Harder!!! I have no internet problems, speed above 30Mb, ISP OK. This started after the latest Mavericks update, and Yosemite is coming... I wish the tech guys try harder to update this bug, this game was awesome now useless.
