Hi Nijel ,
No, self-hosted server isn't affected in any way because it doesn't require our hosted service to work. It is a completely isolated/autonomous solution.
My bad! I wasn't trying to break the rules on purpose, I just find the Windows Viewer is much more reliable at maintaining multiple host connections than the Linux Viewer is, and I prefer to use Linux so that's the only reason I was using the program that way.
No worries ) You should just apply your RU license key in RU Server as described
here. While any paid customer can still use RU Server in the "free mode" , registering it with their RU key will extend their allowed connections via that server (it will bring this number to that allowed by their RU license). So if you have a paid RU license and you use RU Server it's always a good thing to register RU Server as well.
Hope that helps.
