Has anyone tried Rogue Trader on Luna Gaming from their GOG library? Does it even support online when playing it from the Luna Cloud? What about Luna Couch Online Co-op?

I'm considering it buying Rogue Trader and running it this way, since my current gaming PC isn't beefy enough - nor has enough free storage at the moment to run it. I know I know, past time to back some files up... and get a better gaming rig but such is my sad reality at the moment.
