Remote Management can't connect if local was ever used

[CasaDelGato]

I have Blue Iris running on a machine in a closet, running as a service. I usually use another copy of Blue Iris at my desktop to manage the remote one.
I've found that if I VNC into the remote machine, and run the Blue Iris GUI (mainly to check for upgrades), then exit Blue Iris - it leaves the service thinking that a user is still connected.
When I try to run Blue Iris and connect from my desktop, I get the error "Trouble connecting, remote already connected".
The only way to clear this seems to be rebooting the Blue Iris machine, and making sure that I do NOT use the Blue Iris GUI on that machine.
Though, Reboot only works sometimes. Not working today, so I can't use Remote Management.
(and yes, both machines updated Blue Iris today)

I've updated Blue Iris again, and it STILL won't let the remote Blue Iris connect. Still insists that the local one is connected.
