Hi DamianIf I use ActiveSky in Online-Mode, the METAR process complets and then the program crashes during (I asume) the Winds Aloft initialisation.I turned of the WindsAloftSimulation - same error.ErrorMessage:Run-time error5Invalid procedure call or argumentThe program doesn't crash in Offline-Mode, but I get an error when it tries to download the WindsAloft-Data.Error Message: Error or timeout downloading cycleMy System:Pentium 4RAM 512OS WinXP SP1Best regardsAxelP.S. I believe Hermit EGBG reported exactly the same problem

Are you running behind a firewall or running AOL?

I believe this is a bug since I can recreate it at will. I have sent Damian the info via e-mail, I'm sure he will be reporting back after his holiday.Are you using a proxy to access the internet?

Hi AllI finally found the reason for the crashes (Error5), I had the program "AdSubtract" running in the background.After shutting down "AdSubtract" the error disappeard, I tried itseveral times so I'm quit sure, that this caused all the trouble.Now is only one thing left, I still can't download the WindsAloft Data.I also turned off my firewall, without any success and I'm not on the AOL-Network.regards, Axel
