ALright! now i have been testing fsx! First of all i want to thanks Dickens for the solution!
OK Robert Listen now, i want you to TOTALLY uninstall everything! even the windows if possible, and get a FRESH windows.....
And then. Install fsx, and acceleration.
For everytime you install a expansion pack remember to start fsx, so it can load all your updates, if you install everything at once it will crash, so dont try that......
After you have installed pmdg and all you expansion packs. DEFRAG your computer, and then go to your fsx settings menu and click on preview directX 10..
All crashing will stop, i dont even have a problem with replay now.....
Finally
