I am wondering if someone could help me as I tried everything I could think of. I have plane 10 with the Jar Design A330...I manage to set up everything properly and file a flight plan. I manage also to ask for clearance. But as soon as I click on request taxi, nothing happens at all.....no response whatsoever...I have no idea what the problem is. I checked all frequencies even using the ATC box and still nothing. Any ideas?
