- install direct play if isn't
- set compatibility mode to XP
- deactivate all enhancing graphic options and run game as 16bit color maximum.
Then try again and start testing 1024X768 or 1280X768 wide-screen. Higher resolutions cause problems - depends on graphic cards some cause errors some not. But in general I would say downsizing graphic settings work fine like deactivating vertical synchronisation for example will enlarge fps rate again.
- deactivate music players, close ur browser windows and stop all processes who can cause potential conflict to old mc program.
