Do you remember if the last days something changed or updated on your computer?

Best regards

您是否還記得過去幾天計算機上是否有更改或更新？

最好的祝福

Can you fully uninstall the application from the menu Preferences > Advanced > uninstall and check before to remove configuration files? Then download the application and install it and see what if working properly?

您能否從菜單首選項>高級>卸載中完全卸載該應用程序，然後再檢查以刪除配置文件？ 然後下載該應用程序並安裝它，看看是否可以正常運行？
