The way to access your sticky notes after trial expiry is to take the notes data to another computer and access the sticky notes using  
Notezilla .
On the current Windows PC, run  
Notezilla  Troubleshooter to take a backup of the notes data. On another PC, install  
Notezilla , and then run  
Notezilla  Troubleshooter to restore the backup that you had taken in the first PC.
