Dear Support Team,

I would like to use 3 additional instances of SC on the same PC (so in total 4 with the main instance) to make a better use of the cores of my CPU (and the 4 screens I use).
I am with IB and using the SC Data Feed. Bringing up 3 additional instances following the instructions provided here
http://www.sierrachart.com/index.php?page=doc/doc_DTCServer.php#UsingDTCServerForDataAndTradingInAnotherSCInstance
does not work:

I am getting only market data from the SC Data Feed in the first additional instance (and the main instance) and this only if I open firstly a chartbook in the additonal instance and then in the main instance.

Thats the message I receive from the Log File when I bring up a second subinstance:
"SC Data - All Services | Logon error received from server: Limited to one connection per username for the requested data source. | 2016-06-13 11:02:52"

Is it possible to use more than 2 instances (main and subinstance) of SC?

Thank you!

Best regards.
