Keep getting connection errors

HeatherA

I play several games and Scrabble is the only one working.  I keep getting  A net error occurred, please try reloading the game. or connection lost, please reload the game.  My wifi is fine and this is the only problem I have on my new MacBook Air.  It was all working then just stopped.
