Can't start cubase Pro 9

Hello,
i can’t start Cubase PRO 9.0.30.
Every time i try to start it Cubase crashes with message: “Cubase quit unexpectedly. Click to reopen to openthe application…”.
I tried to reinstall it, but no luck.

I’m on MacPro ( Late 2013 ); El Capitan 10.11.6
3,7 GHz Quad-Core Intel Xeon E5
16 GB 1866 MHz DDR3 ECC
AMD FirePro D300 2048 MB

Hi,

Could you send me the crashlog, please? You can find the crashlog in the Console Utility of macOS.

You cannot attach it here. Place it to Dropbox (or similar service) and send me a link, please.
