Tried uninstalling and reinstalling and still the same problem. FlightTeam KSFO also has the same problem
Have you installed the Stand-Alone Addon Manager AFTER all the sceneries ? Try to download and install the Stand-Alone Addon Manager again, because we just updated its installer.
If still doesn't work, you can activate the Simconnect diagnostic mode:
Open notepad, and copy the following text:
Save the file as SIMCONNECT.INI in this folder:
Documents And Settings\YOUR LOGIN NAME\Documents\Microsoft Flight Simulator X Files
At the next FSX launch, you should see a text window with diagnostic message, that should tell what's going wrong. Let me know what you are getting, so we can have an idea what's happening.
Only the first few lines are important: if the window scrolls too fast, you can use the "Pause" key on the keyboard to pause the scrolling. Post here only the first 10 lines or so of the diagnostic, but it's important you post the first 10 lines.
