Updated weather (static) got blocked...

I have a problem with my updated weather (static).Normaly, when you select this weather option, the latest weather is downloaded and used and then stayes fixed during the entire flight. This has not been a problem until recently.I started a free flight and i knew that it was raining. After entering the aircraft, it was raining. So far so good.The next day however, it was a clear sky, bright winter sun so i expected to see this when i got into the aircraft. But i was amazed that it still rained.As i test i switched to real weather (updated). After the weather data download, the sky was sunny and clear. So i switched back to updated weather (static), again the latest data was download but upon entering, it rained again?Since then, i always have rain when i enter my aircarft on that particular spot when i used the static weather.Is there a possibility to reset this?
