I think the last version of this bundle was 2016 or 2017 (maybe even when Gig Performer didn’t exist at all).
The website is down and the bundle is abandonware.
Like rank13, I also recommend that you find plugins that are stable and actively maintained.
If you still want to take another shot with this bundle, read this blog, try to delay the plugin initialization and then (if that doesn’t work) try to wrap it with jbridge.
