Main character broken

[Sluban]

In some moment when I was playing on Korriban my main character got broken. He can't use any objects which trigger script(terminal etc.), he can talk with NPC, fight or loot containers. He also not follow other characters when they are active. Other characters work normal. I can't complete game because, I can't use any objects in tomb where you must play only with your main character. Someone know how to reset your main character? Or activate his scripts?
