Cant save the downloaded real weather

I used to be able to save a downloaded real worl weather, with a
situation.
When I then load the situation later on, the weather data from the
time I saved the situation is loaded. If it was raining and temp was
12 dec celcius, its the same when I load the situation.
If I now load the old saved situations, the weather data is also
loaded.
But if I today generate a new situation, download the latest real
world weather, and save the situation, and then later load the newly
saved situation, the weather data dosen´t load. The weather is "reset"
to some kind of default value, with clear visibility, no clouds and 15
deg. celcius all over the world...

I have removed the cookies in the explorer and moved the temp files
folder in explorer, just as Microsoft on their supportpages guides me
to do. Nothing helps!
I also have been udinstalled and reinstalled the FS2004 two times, but
nothing helps...
Any ideas what I should do?
