I installed FSX Acceleration on a WIN XP SP3 system. My version of DirectX was 9.0b, and with FSX that ran just fine. After the install, FSX would not startup, stating that my version of DirectX was incompatible. It also said I needed up download the latest version. Here's the kicker. For some reason I cannot download 9.0c. It just won't work. I downloaded DXWEBSETUP from MSFT's own website, and when I click that it just times out. I have been online with MSFT help but that is totally useless. I noted another forum that said someone else had the same problem but already had 9.0c installed, so I'm not sure if that is the solution anyway. My video card is a PNY 8800 GTS 512 Nvidia chip (new also), and I have 1 gig ram. I uninstalled FSX Acceleration and now my FSX runs fine again, so I know it has to do w/ the Acceleration pack. Any suggestions would be much appreciated.
