When I try to run Zorro on the second machine I get the unhappy face in the top right of the chart to tell me it's not working, and "Error (see log)" in the top left. The log reads:
"[Account number] previous successful authorization performed from [IP address]".
It sounds like you are describing the MT4 bridge, but your description of the problem is extremely unclear.
Make sure to install the MT4 bridge 100% correctly. Follow the steps down to the letter.
By the way, the MT4 bridge is free to use in demo mode, but you need to get the Zorro S license to trade live.
