Kotor 2 Bug Question!!!!!!!!!?

ok so i bought a brand new copy of Kotor 2 for computer. Its been running fine until I get to the secret Academy. Atton and Kreia are behind me if i talk to atton he has 2 options says cheat node skip to the conversation with the jedi chick or continue with kreia conversation. the Kreia conversation does nothing. If i choose the other one i go talk to the jedi Chick. i talk with the lady and she leaves. then i talk with the handmaiden and she says my friends are in the chambers and then asks what the force feels like. i tell her then that conversation ends. Bao Dur is unconscious in his cell in the holding room and atton and kreia wont follow me so i cant get on the ship without them. i have never installed any mods for this game or anyting. WTF DO I DOOOO! I know there has got to be a fix. HELP!
