nuendo live doesn't launch...

I got a big issue with Nuendo live, i just bought it and when i launch it, it blocked and in the process list it is labelles in red as ‘‘nuendo live doesn’t respond’’
it’s a big pain because i need it to record a tv show next week
i’m on Macosx el capitan 10.11.4
please if you can help me, every thought will be a big help
thanks :frowning:

Sorry but i didn’t get any help with these,
it works properly on yosemite (fortunatly i got another mac for recording) but impossible to launch nuendo live on el capitan.
any help would be great.

all i got is this freeze screen
