My aol "games" SCRABBLE has worked for over a month. I seem to have "modified url."?

Suddenly I cannot play POGO Scrabble free on aol. Have been playing for a month- no problem. I successfully click on "GAMES" But Tonight it goes to a screen that says "URL modified. Current URL is invalid." No instructions given how make valid again. Other games click on and work fine...just Scrabble won't play.
