使用mysql启动时，提示了一个错误！

High Severity Error

Unhandled Exception

Root element is missing.

点击show details按钮显示

at MySql.Notifier.Properties.Settings.get_AutoAddPattern()
at MySql.Notifier.Classes.Program.ChangeAutoAddPatternDefaultValue()

原因我不清楚

解决办法是：删除C:\Users\Administrator\AppData\Roaming\Oracle\MySQL Notifier文件夹的所有文件，重新启动就好了
