Okay, so I download SP1, and installed it. It gave me a message saying "SP1 was successfully installed", or something like that. Is that all I need to do, does it automatically get set up with FSX?
Not sure exactly what you mean but SP 1 should work if you got the "Successfully Installed" message. To check right click on the FSX.exe and choose "properties". Next click on the "Version" tab and see what that says. If it says this:
10.0.61355.0 (fsx-sp1.20070510-2038)
Then you are OK.
