Hm, don't know what is meant by "2 Games" resp. "both games"?
Do you mean your two installations - trying to connect them with each other? If so I just tried here with the full version, not the demo.
Sorry regarding the patch. I forgot to provide the link. That patch can be downloaded e.g. from
here and it needs to be applied to every NAPALM installation individually.
The patch contains a readme and installation is quite easy.
