i recently installed the newest software we received from the "Building Design Suite - Premium 2013".
The problem with Revit 2013 is now that when I open an existing or any other drawing Revit says to me that there is no Material Library installed??? I tryed to reinstal the software but the message comes again that there is no material library installed. In the installation menu i searched the material library and there is an option marked that the medium library is installed.
You may want to try a repair install. Insert the media or whatever you have, click run and when given the choice pick Repair. If that fails you may have to do a clean uninstall. Follow all the instructions on this link:
