Adobe Garamond "SEMIBOLD" Broken

I was using Adobe Garamond on a file. It has been working fine for the last few weeks. After updates for windows and all adobe products, every use of Adobe Garamond in “Semibold” disappeared from each version of our file, and I could not export the file as a PDF. Every other subset of Adobe Garamond is working great, but if I try to use “semibold”, the text disappears.
