That Conversation Node Error thing sounds like you have the game installed as a language other than English... K1R is only English at the moment.
As to your issue here, that could be related, but if you have a save from before going to the swoop track, try deleting the tar_m03af.mod from your modules folder and then trying the swoop track. If that still fails, try warping to tar_m03mg to do the race.
