Yes--I was just out at the FS SP1 & SP2 website.  It states that third-party software may not work correctly with one or more service packs not installed.  I will start with SP1 and see if that works.  If not I will install SP2 and then finally the Acceleration pack. Thanks David

Hi David,

If you don't use Acceleration for FSX, make sure that you have installed both FS SP1 and SP2. They are essential and indispensable part of the minimum requirements to be able to use CS planes properly.

You must install SP1 before installing SP2, so download both and install them.

Hope this help.
