My atc has suddenly disappeared. When I press the ' key, I do not get the ATC dialogue window anymore, with any planes, on the ground and in the air. I am suspecting a lost DLL but where do I start looking. Anybody heard of similar problems?Thanks

Coincidence! I flew from UK2000's St Mary's airport and headed toward France. I had ATC until I left the island. I as ingressed over land, I saw an airbase and hit the ATC button. The result was nothing. I recall it was a MIL AB but I need to go back and look at it in AFCAD to verify if there is an ATC set for that base. Julian

Try pressing the accent (`) key, rather than the apostrophe (') key that you indicated in your post you are using. On US keyboards, it is the lower case item on the tilde (~) key.Paul

Thanks for the tip, but after 3 days of non-service, it has decided to work again with the standard key ('). Don't ask!

OK, I won't ask!! :-lolBut do check your key assignments under options in the FS menu. Also, check the listed keyboard commands for MS, it shows the accent (or tilde key if you prefer) key as the one for ATC. It could stop working again. :-)I am assuming a USA/English keyboard. Paul
