It appears you installed FSX then Acceleration then FSX SP1? If you have Acceleration installed, you do not need to install SP1. Acceleration contains SP1 and SP2 versions so, if you installed SP1 after you installed Acceleration, this could be causing your problem. With the preview box being black, that indicates to me you might have a memory issue and your aircraft are having problems showing up in the box. Make sure you have the /3GB switch installed and return your FSX.cfg settings to the default and see if that fixes it. Windows XP will not allow the use of DX10 in FSX, only DX9. Hope this helps!Best regards,Jim Young
