FYI (just getting the warning out)
NPAPI ("Netscape Plugin API") was disabled today with an update to Chrome v42.
To enable, follow this link in Chrome: chrome://flags/#enable-npapi
Close all instances of Chrome (tabs & windows) and restart Chrome. Chrome should continue to work with Silverlight until around September when NPAPI support will be removed. See link for more info: http://arstechnica.com/information-technology/2015/04/chrome-starts-pushing-java-off-the-web-by-disabling-plugins/
Push users to IE or another browser or go full OOB to continue support. Hope this helps.
