So, I am running an up to date windows 7 pro 64bit with google chrome 42.0.2311.90m
When chrome updated the plugin was no longer seen but worked fine in internet explorer. I don't like IE
I googled around a bit and it took me a while to figure out the solution.
Google is completely depreciating NPAPI plugins.
you have to go in and manually re-enable.
So from your google browser go to chrome://flags/#enable-npap in the address bar
scroll down until you see Enable NPAPIMac, Windows
click enable.
chrome will ask you to relaunch.
and you are good to go.
