- Go to Task Manager, select Processes and end the process Notezilla .exe
- Now open the folder %appdata%\Conceptworld\Notezilla in Windows Explorer. To do this, copy this path %appdata%\Conceptworld\Notezilla and run from start menu or open in Windows Explorer. This is the default data folder. I assume you haven't change this location in the past.
- Inside the folder, you will find Notes8 file. Just rename the file to something else
- Run Notezilla and see if it shows up successfully.
If it shows up successfully, then you may have to restore notes from backup.
Watch this video for more clarity:
The video in above link assumes that you have access to Notezilla . However, if you don't then you can open the Notezilla data folder by opening the folder %appdata%\Conceptworld\Notezilla and follow the instructions given in the video. Copy this folder location and open it in Windows Explorer.
In short, you would open Notezilla data folder %appdata%\Conceptworld\Notezilla and also open the backup folder %appdata%\Conceptworld\Notezilla\Backup and copy Notes8.db file from backup folder to the data folder. Do all this when Notezilla is not running. Notezilla keeps 5 backups. If you cannot restore the previous days backup, then try a little older one.
