While I'd love to be able to help you, I've not even managed to open more than one instance of CoH on my PC. When I run CoH.exe it tells me I need to run the patcher, so I run that, fine. Then I try to run another and it tells me I can't run more than one instance. Same when I am trying to set up 5 regions with Keyclone. The regions load, all with the little message telling me how I can't run more than one instance. I would love to know how you managed it.
