[CLOSED] Traffic Controller disappears

[707Liner]

Hi,
I'm able to start TC and it runs for a short time, maybe 5-10 minutes, but at some point it then stops and disappears.
From what I've noticed, it looks a lot like something in Windows is blocking it or maybe isn't running that it needs. It may also be related to when the AI aircraft needs to talk to ATC it then kills TC.
Any ideas?
