My previous installation of Lianja App Builder was running successfully on my Windows-10 PC C-Drive.

Due to C-Drive space constraints, I decided to uninstall Lianja App Builder from C-Drive and re-install on my D-Drive.

After re-installation on my D-Drive, I discover a few items was missing.
1. Sample Database like Southwind, lianja and Cloudlintest were missing.
2. On the Home screen, I only see "DEVELOP" tab, "ADMIN" and "EXAMPLES" tabs are missing.

Please advice how I can recover the 2 missing items.

Thank you.
