I have downloaded the Revit 2013 Hotfix x64, however, the Readme link on the update page doesn't work, I can't figure out how to install it or where to save the extracted files.
Also, I have been getting a "fatal error" when I try to change the material on in edit type of structural wall... the pop-up window opens, but then it freezes and I get the Fatal error box asking if I want a 'recovery file' saved. Will this Hotfix correct that error too? I have attached the screen shot of the error, and sent the error report 3-4 times with no resolution yet.
