Keeps going backward

I really enjoyed palying this game, but suddenly every time I click on a card, the game goes backwards. It actually undoes the last move I made. If I keep clicking, it will actually go all the way back to the start of the game. This is extremely frustrating and makes the game all but unplayable. There is no way I can see myself paying to endure this frustration.
