Hi;
I’d be really interested to hear about what problems you had. The only reason I know of that would stop you activating the plugin would be having a PHP installation that’s out of date. The plugin requires PHP v5.5 or higher.
You should have received a notification saying that though?
If you had some other problem feel free to drop me a note here and I’ll see what I can do:
