I am constantly adding new mods to my game and this time I edited the "Mod Manager" skyrim.INI file and now cannot get game to start. I have since gone into the INI file and deleted the entries I made, but still cant get it to start. The exact message I get when trying to start the game thru Mod Manager is : " The procedure point D3DX9_43.#148 could not be located in the dynamic link library d3dx9_42.dll ".

Do I need to uninstall the game and reinstall, or Reinstall the entire Windoes 7 operating system??

Thanks for any help.

before you do something drastic like reinstalling windows ........get the windows updates first and reboot PC after finished

update your video card drivers & any other updates you need

in steam check the games go to SSE / property / local files and click verifies game cash integrity ........this will download any missing files that may have been removed or corrupted

make sure you have the latest Bethesda updates

when doing any editing on Skyrim.ini or Skyrim.pref its strongly recommended to back up both files just in case you have issues like these

there is a small app called Beth.ini that will do this & you can configer heaps of settings with out you needing to copy and paste codes

if all of the above fail

go to your documents /my game /SSE and cut and paste both files (ini & prefs) to your desktop) ......now run the game with out the files, you should get the Skyrim options window & it will detect your card again, if you go and look at the folder where you removed the files you will see two NEW files created (default)

now after doing all of the above steps your game should work

anything you do always back up the files first ........one wrong code in the wrong place, a wrong number can stuff up your game

You shouldnt need to reinstall the OS. Does Skyrim start outside of MO?
