Thank you for trying  Notezilla .
The master password cannot be retrieved. So the sticky notes cannot be retrieved. However, you can reset the master password. Once you reset, you will be able to delete those notes.
Click on the Forgot Password link shown below to reset the master password. To access  Notezilla 's Preferences, right click on  Notezilla  icon and choose Preferences from the menu. Then click on Advanced button and then click on Master password button.
