In very rare scenarios it could happen that you get this error when starting a sport in Live Score:

Error when starting Application. Unable to cast object of type xy...

When you start Live Score in a specific sport, it will automatically reload all previous settings and layouts of that sport.
Somehow it happened, that a layout from a different sport is existing in there.

The solution is easy - we just need to delete that previously cached setting.

For this, open the Log/Cache directory from the Startup Screen with the Sport selection in Live Score.

Then backup and delete the "cache_XYZ" file of your sport.

This will remove all settings and caches of that sport.

If you now restart Live Score and select your sport, it should work again!
