I've been contending with this off and on for a few months now, the Slate FGX plugin would not load complaining about the licensing service not being available, even tho the rest of the Slate plugins could activate and run just fine. The exact error was:
"The licensing service required to activate this software is not running. please reinstall the product or download and run the iLok License Manager installer here: http://www.ilok.com"
I'd restart the iLok service, usually it would sort itself out. Today the plugin wouldn't load at all. Quick google searches found this -

They posted an update for FGX. Uninstall the current version, install the new one, It fixed the problem for me.

Posting in case anyone else ran into this weirdo problem. Cheers.
