Download and install a free program called quickpar. once installed click on one of the star wars begins par files (make sure that they are in the same directory as the rar files) It will now automatically scan the files . once the scan is complete just click repair (unless automatic repair is already ticked then it will do it automatically once the scan is complete)

Thanks for that Adywan, ive followed your instructions but there doesnt seem to be anything to repair. There just isnt the download location for SWB_FINAL.part065.rar within the original DLC file..

edit: problem solved! (phew) Thanks Elbarto!
