Cubase 9 crashed at startup

Hi all - hope you can assist with my problem

Hi,

Installed c9.0.1 on my MacBook (15" mid 2014) with Yosemite 10.10.5 with no issues!
Then installed c9.0.1 on my iMac late 2013 with same OSX version and 32GB Ram and it crashes on startup.
Installing new did not help
tried starting 8.5.30 with then at least got to the Hub
I started a project and then C9 crashed
I shutdown the iMac and restarted
8.5.30 runs again
c9.0.1 still crashing with error:

Issue resolved (i hope)

Cubase did have a problem with my UR44 at start.
When i switched the UR44 off it started without problems.

I reinstalled the UR44 drivers new and now it seems to work w/o issues.

Thanks,
Carlos
