Reading Race 1a: CVC word LITE

Question

Hello my name is Ana Fisher and I work at a school in the city of Pico Rivera, CA. I am trying to have our kindergarten students use the Reading Race 1a:CVC word LITE but it keeps telling me its not compatible. Is there a way I can have our kindergartners play this game? or is there a fee to use this game. You can contact me at afisher@erusd.org
Thank you,
Ana Fisher
