I have been playing the single player campagn for quite a while now and I have reached the part when you enter Luskan. The thing is, when I try to get into Luskan the game loads into a multiplayer gamespy region and I cannot continue my single player game. My 13 level sorcerer doesn't exist any more and the highest level I can choose of her character that is saved is level seven. It is taking me into the game as if I haven't even played the first two chapters. What is going on?

Hmm, this is a new one. While connected to the Internet, run the update program from the first menu screen. See if that helps at all. If not, try severing your Internet connection before playing. Let me know if that helps.

Something like that could possible hhappen when you have used console commands to beef up stats xp etc of your char. He will be invalid then and you cannot play him in singleplayer to the next chapter. Maybe that applies to mplayer use as well. Just a thought.
