<h2><font color="red">i can play as many multiplayer games as i want. Unless i play a single player game, as soon as i do that, i lose all multiplayer capability. I'm not trying to switch something from single to multiplayer, but after i start playing a single-player game, i cannot even host a multiplayer game to create a new party. I have to reinstall...any ideas why?</font></h>

oooh, i make big font. i can read now!

What happens when you try to play a Multiplayer game? Does the game crash, or what? If you tell us that, we can help you.
