I now have X-Plane 12 installed and running and have an addon called LiveTraffic 3.0.0.
Everything was working fine for the first 15 minutes, airlines were taking off and landing at Heathrow (EGLL), then I received the message:
OpenSky: Used up request credit for today, try again on 12-Sep 21.25 and the aircraft disappeared from the Aircraft Info List and from X-Plane 12.
Can someone please tell me in simple terms what I need to do to get the aircraft back permanently.
Thank you. Mel.
