You'll be lucky to find anyone who bothers trying anymore!
It's truly awful for it's reliability.

Latest is that Gamespy have pulled all FSX support and servers.

I'd recommend FShost instead

Never had any trouble myself either, and for someone who has simconnect issues which cannot be resolved without re-installing windows, i cannot use FSInn or Vatsim or any other host unless it is similar to that what Gamespy had set up.

LAN sessions still work via hmachi or something similar, but other than that is Fsinn or FShost
