Has anyone else lost materials in the 7.8.80 update? I updated some time before the Christmas holidays, and when I came back to resume my work, I noticed the library had changed. Things like XPS insulation became XPS with CO2, but others, such as Concrete - Light Weight and Concrete - Heavy Weight, were no longer available. I'm also missing Plywood Douglas fir). I've reinstalled the redistributable libraries, etc as if I were back to a fresh install, and I can't seem to get the old library back via installs.
I am even missing boundary conditions like Interior Normal.
If I open an old file, I get the library conflict notice and can choose to load the library from the file rather than the program. However, this will only provide me with items I used in that file specifically, and I'm unsure what else might be missing.
Any ideas?
