Hello and thanks for your help,

I am running 4 instances of SC on my debian based PC without any issues on trading evaluator mode. I attempt to do the same with my live account and cannot logon at the same time on all 4 instances/sessions. I get a window pop up saying "Connection error message from service: CQG WevbAPI received logged off message. Reason: your session was closed due to concurrent session."

I have also coppied the message log
