nDisplay error

I’ve been trying to launch nDisplay launcher along with nDisplay listener. The first time I did it, it seemed to work. Now I get an error message everytime I hit “Run”. Here is a log of the error:

I run them as administrator, have done a system restore, etc. I’m not sure what’s going on here. I’m trying to setup tracking for an eventual P2 LED panel coming in, but I can’t get past this basic step. Any help is welcome!

I’ve just run into this error. Any fixes or work arounds?

Hello @**AnnunakiBro. **I tried swapping out the default IP address ‘’ in your cfg file to the IP address of your cluster node.

Eg: [cluster_node] id=“node_1” addr=“insert your IP address here” window=“wnd_1” master=“true” sound=“true”
