Very Buggy, no support despite paying

This plugin conflicts with opt-in pages that are installed in widgets, considering that collecting opt-ins is a major goal of my site, can’t use this.

I tried to get support but they do not respond (I do not think they speak English) considering I paid for this plugin, this is disappointing.

Now I get this error and support requests go unanswered, they just want your money.
