Multiple OpenVPN connections

Hi,

I'm trying to setup multiple OpenVPN connections on my router at the moment, one connection is purely for one PC, this works fine using the policy rules setting. However i want a second connection to be for all the other devices. I can't find a way to get it working, i simply get "Routing Conflict" as the error message.

I know practically nothing about routing so not sure where to begin on this.

Thanks for any help!
