A coworker has been building a materials library for several weeks. Today, Revit 2013 crashed, and since then, when we attempt to load the library, it reports, "No assets in this library". We've tried opening the materials library from other computers running newer versions of Revit, and all fail to load the library. Is this a case of a corrupt .adsklib file? And if so, can it be recovered? The file is about 30MB, and contains a lot of information that is readable via a text editor. Is it possible to modify this file in some way to make the library load? Any help would be greatly appreciated.
