Restoring default materials

[Anonymous]

I have accidentally deleted all concrete materials predefined by program defaults.

Now I need to restore those materials.

I tried "restore initial program settings" in the job preference but it didn't work. I repaired my product using the installation wizard and that didn't help either.

Please let me know how to restore all materials that were defined by defaults.

Thank you
