hi there and welcome
You need to install it again. It is free and you can install it from my link below
Click on the Free button and it will then install.
Once installed, you can then access the game.
If you have any problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
