Post From: Sierra Charts on two computers for different trading accounts not working

I have a SC installed on two separate computers, one is configured to use the SC data feed and trade on Interactive Brokers, the other is configured to use CTS data and trading.

When I try to run them simultaneously, only one is allowed to connect and I get :

IT does the same thing if I try to run them on the same computer.

I have a level 5 subscription so I should be able to run 3 instances of SC, correct?
What am I doing wrong ?

Each of these instances will connect successfully if the other is not activated. I don't understand the conflict.
