Wow, I found the answer in another forum searching in it, I'm so happy now I can fully use the simulator. The problem was that since I have that new version of Internet Explorer 7, the Simulator wasn't working with it. The solution is:
You have to Backup the file named oleacc.dl in another folder.
The file is located in the Root Folder of Flight Simulator 9.
I guess that file didn't let the Simulator work it's internet magic.
Thanks all who tried to help me,
and I hope this solves some peoples problems.[/b]
