50% CPU load and overload during render online

Again, the same problem. I just upgraded my setup to RME HDSPe MADI Pciexpress and SSL Alpha Link AX and my problem is still occuring and pissing me off!!! I just lost ONE HOUR trying to render final mix. And every time the chorus ends - from 50% it goes to 100% instantly causing overloads.

STEINBERG PEOPLE - PLEASE ANSWER ON THIS QUESTION THIS TIME!!!

P.S. After the drop out - there is now sound coming from Cubase - I need to restart it to get sound again. freakin joke
