I can't get it to work with just 2 characters on Windows 10, it runs both as hubs. I'm running both characters on the same laptop but each on their own screen (laptop screen and 1 extended monitor, not that it should matter). I tried the advice in this post and the one linked, but no go.
The odd thing is it did work the first time I ran crosscharcom2, but subsequent tries with the it and the regular crosscharcom just bring up a hub on each.
I just gave up and went back to mouse move/macro.
