Hey!
I have the same problem. I cannot connect to my VEP5 server on my slave. BUT if I open an old project it will trigger the instances on the slave and everything is open. But I can't start anything new. Problem is in Pro Tools AND DP8. Everything on the last update. I don't have the problem with an instance on my MacBook, where the DAWs are running, only on the Slave, but the connection is ok (otherwise it could not trigger the old ones?) Don't understand this issue :/
Best regards
Michael
