I'll try "ATC=off" in FSUIPC init as suggested...Thanks
But Ive been flying FS9 since it first came out and this is the first time this ever happened...
I must have done something?
I have never had the issue myself but from that discussion several people have (while using another third-party programme at least). There are other things that can cause the same error, irrespective of third-party ATC add-ons, so the conicidence of using such may just be a red herring.
You might find my page at
