Hi, Upon installing and using Revit Architecture 2012, I noticed the materials library seemed slower than in previous versions. Today, I tried to repair/ reinstall and a warning came up saying a file couldn't be located. Is it possible to receive just that file or would I have to uninstall and reinstall ? The file is C:\autodesk\autodesk_revit_architecture_2012_english_Win_32-64bit\x64\rac2012\programfiles\autodesk\root\program\textures\environment\cross\reflect.exr. Initially I downloaded the student version via the website. Aside from this issue, the program works fine and I'm happy. Would the abscence of this file cause the materials library to run slower? thank you.
