Just submit your email here https://jstuff.wordpress.com/jbridge/updates/
and it will send you the latest version per-registered to your email.

It is good to have an alternative to try as well if you have any issues with JBridge.
The NetVSTHost for Mac (made with WineBottler) should run Windows VSTs on a Mac.
But you won't get vst sync like you do with JBridge.
