Rekordbox Unexpected application error. Help!

Hi there.

I am using the software on Mac OS El Capitan (V10.11.3)

So I booted up rekordbox for the first time in quite a while and when I luanch it, it says a new verson of rekordbox is available, 3.3. So I download, install and launch, and as soon as the program tries to start, it crashes and gives me that error message.

It also prompted that there is a new version out, 4.1. So I install the latest version on your website thinking 3.3 might be an outdated build.

When I try to start that one as well, It immediately crashes and I get the exact same error message "unexpected application error".

So I have 2 versions of rekorbox, 3.3 and 4.1 properly installed but both of them crash on startup.

Any ideas anyone? Please help!
