My game is not opening, before I changed in settings the 3D options, and now its not opening, Showing..

The timeout message my be a temporary problem with the network connection (either your device of the game server). However if this remains then there must be a glitch with the setting and your device. Possibly you can contact the developers to report this.

If you have used the option to Bind your game to an external account then you should be safe to uninstall the app and reinstall it. You can then log back into your game using the bound account details. If you have any concerns though please check with the game support.
