updating the application-server never finishes

I have updated on my mac a Servoy 6b3 version to the final 6 release.
Everything went smooth, except the last step, Servoy Developer asked me to update the application-server to the latest build number, but if never finishes… I have waited for more than 30 minutes…
What can I do??

Reinstall with the installer ?
Of course if you installed the bundled PostgreSQL you want to move that over after the install (make sure PostgreSQL is not running).
