When I kill the three Jedi Masters at the tomb of Freedon Nadd, a yellow-armoured Mandalorian whose name I can't remember comes to tell me how heroic I acted and all that, and when I ask about what happened to my main character, he starts telling, after which I should normally start playing at Iziz with my main character. However, this is skipped and the next thing I see, the leader of my secondary party (Disciple in my case) is at the Mandalorian camp on Dxun, being introduced to the Basilisk War Droid, but I cannot enter it, and when I try to enter the Ebon Hawk, the game crashes (probably because I don't have my main character)
Also, I noticed the there is a file called AR_ERROR.LOG in my SWKotOR2 folder, containing only the following message:
Names Differ: PMBMN pmbnm
Any help would be greatly appreciated, since I cannot continue my game at this time.
