Post From: Running Sierra on two computers with Logon error message

Hello, I have been using Sierra with two instances on the same computer. I wanted to trade long side trades in the main copy and short side trades in the second instance. Both of them being directed to one account at Interactive Brokers. I realize that one open long trade from one instance and one open short trade from the second instance would mean that I did not have any open contracts at IB.

I do not have an account at IB yet so was just testing everything, all worked well except I was running four large monitors through a USB hub, today two of the monitors were not working. So I decided to reduce the number of monitors on one computer and set up Sierra on a second computer. I deleted the second instance and made sure that in General Settings that it did not open automatically the second instance.

I copied the Sierra3.cfg, GlobalSymbolSettings.xml, and KeyboardShortcuts.config into the correct folder and then the data files, charts etc. into the Data folder of the Sierra folder on the second computer.

But now when I try to open Sierra on two computers, I get the following message:
SC Data – All Services | Logon error received from server: Limited to one connection per username for the requested data source.

I wonder if there is somewhere else that the second instance that I used to open when everything was on one computer is still being referenced and that the application thinks I’m trying to open three connections, Sierra on two computers and the old second instance that I’ve since deleted.

I currently subscribe to Comex data. I had read elsewhere on your site that we could install Sierra on two computers and run them simultaneously. So I’m not sure why I’m getting that error.

Thank you for your help.
