Desappointed

I bought this plugin a year and a half ago, for a site to a client and suddenly it stopped working. I was really happy when I installed it.
But few days ago I saw there was a problem, the plugin didn’t have any info on it, I tried to reinstall but nothing so I finally changed for another one.
It’s a shame people don’t update their plugin when you have bought it.
I left a feedback and will probably never have a response.
