I have an Adobe Illustrator document with linked Photoshop files which no longer opens after installing the PANTONE PLUS SERIES libraries. How can I fix this?
Most likely, the Photoshop file is using PANTONE colors from the older PANTONE MATCHING SYSTEM libraries. Since these libraries are not active within Adobe Illustrator the colors are not recognized by Adobe Illustrator.
To fix this issue, reopen the linked file in Photoshop, and remap the PANTONE colors to the PANTONE PLUS SERIES libraries. Save the file and relink to the Illustrator document. The file should now open properly.
