La primera opción es reinstalar el programa. When you begin the reinstallation, you will be prompted to uninstall the existing version. Confirm the uninstallation then begin reinstallation of the program.
The second option is to manually integrate the already existing material libraries from either a previous version of the program that exists on your computer or another computer where the program is installed.

General material library: "Materialien.dbd"
User-defined material library: "Materialien_User.dbd"
