Hello Pete,
first thx for your efforts.
I checked all modules which should be changed by the patch and found "weather.dll" not changed. I remember that I replaced the original file by a a "imodified" one from the net. I forgot this and didn't replaced this file with the original one before running the patch.
To be sure that everything is done well, I changed all files to the original one to get an unpatched FS9 version. Then I tried step by step from FS9, FSUIPC v3.30 to v3.40 and then to FS9.1 and v3.40.
And now everything is working well...the Wx + AI gauges in ACS panel and Wx from FSMetar.
Summary:
The problem was an unpatched file - weather.dll - because it was a modified one.
After replacing this modified file with the original one and running again the patch everything is working fine.
Pete, as you wrote in many posts to check all changed files, it was my fault, that I did not checked it well...
Thx again.
Regards,
