When I start Cubase 8 pro I have the message: "No valid EuCon software can be found on the system. Please download and install the relevant EuCon software, reinstall EuCon adapter and restart your aplication. 
I tried to reinstall the program, but it didn’t help! 
Where I can download the relevant EuCon software for Cubase 8 pro? 
What for this adapter is necessary?
