First, you should verify that no invisible items are covering the buttons, as discussed in this FAQ.

Next, you should verify that you are not in a no-scripts zone.

If you’re not in a no-scripts zone, then right-click on your game and choose the “Open” option. If there is nothing in the contents, then you may have removed all the scripts from your game or table somehow. There is no way to fix this, and the game will have to be replaced. If it’s a newer mesh model, you can use our Redelivery terminal to get a replacement. If it’s an older prim G.SL model, you can Migrate in order to receive an updated replacement. If it’s a very old prim model, please see our End of Life article to see if you qualify for a replacement.

If there are scripts inside the game when you open it, the problem may be that the scripts got deactivated, possibly by the estate tools. The game will have to be replaced if this is the case. Follow the instructions above to get an updated, fresh replacement, and see if the problem persists. If it does, please contact us.
