SWTOR: ERROR C12
So I'm getting this, constantly when trying to exit my ship. This program encountered an internal error and will exit. Error code: C12 Failed to load room dat file [/world/areas/4611686025952...
Try the repair utility located here just be careful it doesn't switch you back to streaming , if it looks like it does , close the launcher and re-edit the client_settings file , just mentioning just in case.
check the launcher.settings file after running the repair utility before launching may be best.
